A pair of New York street dancers prepare to tumble and breakdance for the crowd at Washington Square Park. But when they turn the music on, instead of hip-hop, the strains of Tchaikovsky’s "Sleeping Beauty Waltz" came out! What to do? There was nothing to do but dance!

It soon became clear that these guys knew what they were doing. They are professional ballet dancers, as were the two women they pulled out of the crowd to dance with. This is the latest stunt from Improv Everywhere, which they performed several times for the changing crowds that afternoon. Read the details of the caper at their website. A good time was had by all. -via Buzzfeed

A thousand Italian singers, guitarists, bassists, and drummers under the name Rockin1000 got together to play “Learn to Fly” by the Foo Fighters. Watching that many people play and sing together -well- is spine-tingling.

The stunt, a year in the making, is intended as an invitation to Dave Grohl and the band to come and play in Cesena, Italy. Do you think they will?

Oh, in case you'd like to hear the drums and bass only, here's a personal video taken on the scene without a direct music feed.  To hear only the guitar, here's a video from a guitarist with a GoPro.

Update: The Foo Fighters have responded.

Ci vediamo a presto, Cesena.... xxx Davide https://t.co/o3ThIE4QYV @rockin_1000

— Foo Fighters (@foofighters) July 31, 2015

In English, that means "See you soon!"

Update #2: Dave Grohl just uploaded the Foo Fighters’ response to YouTube.

A translation:

Hi Cesena! I'm Dave. Hi. I'm sorry, I don't speak italian... just a little bit! This video... it's amazing! Such an amazing thing... thank you! We are coming. I promise. See you soon... Thank you so much. I love you! Bye

What these Indian girls are apparently doing is manipulating in their minds and with gestures an imaginary abacus. This technique helps them keep the numbers in the man's rapid-fire math questions straight. He can barely keep ahead of them with his electronic calculator.

Don’t park in the bike lane. Seriously: Don’t. Park. In. The. Bike. Lane. It’s not for you and this beefy cyclist will prove it to you. If your car is in the way, he’ll pick it up and move it out of the way. That’s a courtesy. A less polite response from him might be to throw the car out of the way.

Kevin Libertowski is a basketball trick shot artist, but even he was astounded that this one worked.

I made this shot from a trampoline over 60 feet away from the hoop I was shooting on. The shot starts off with a ball in my hands and another in between my legs. I then back flip releasing the ball in my hands towards the hoop, then go immediately into a front flip while exchanging the ball from my legs to my hands, then wait to rotate around a bit and shoot the second shot at the hoop while still in my front flip. Each shot reaches the hoop at the exact same time colliding inside the net for a double swish.

It would have been tragic if any of the cameras had failed on this one shot. Yes, he made many attempts before getting it just right. -via Uproxx

There is a ton of trees in the 365 feet between the disc golf basket in the woods and the place from which the shot originates. But that didn't stop disc golfer Dave Feldberg as he competed in the Maple Hill Open in Massachusetts. Fredberg, with the help of a fortunate bounce off the ground near the basket, made this most unlikely hole in one. His final score was -12; he tied for seventh place, taking home $1,175. Via Uproxx

His superpower is wielding a steel tape measure. With it, he can flip switches from across the room, snatch objects, or use a Porta-Potty. He could probably even cure a rainy day and resolve buried childhood anxieties. He's Tape Measure Man!

Adrian Gonzalez, a first baseman for the Dodgers, leaned over the railing to catch a ball as it arced toward the stands. He almost got it. But spectator Keith Hartley snatched it barehanded right above Gonzalez’s glove. He did this while leaning over a railing and holding and bottle-feeding his 7-month old son.

Like a boss.

The batter was ruled out due to fan interference and the Cubs went on to beat the Dodgers 1-0.

If you’re tired of hearing “Uptown Funk,” then just turn down the volume and watch this lady dance. Shirley Clements is a teacher at Panorama Ridge Secondary School, in Surrey, British Columbia. She’s organized and staged a local dance contest for 19 years, and this past January was her last such show. This special performance was in honor of her retirement.

Clements is 60 years old, but she boogies, shimmies, and even break dances like someone a quarter of her age. -via The Daily Dot

Matt Bray of Project One Life did a video last year in which he learned the Napolean Dynamite dance in 100 days. He’s pretty well perfected the dance, and in this video, he’s doing it in 100 different places! And he only changed clothes about eight times. The video is mesmerizing. It’s a tribute not only to his dance skills, but also the editing that made the transitions so smooth. What it once for the choreography and editing, and then a second time for the locations. -via Viral Viral Videos

If you play guitar, seeing one on a shelf in any store naturally draws your attention -even in a toy aisle. You say to your buddy, “I wonder how hard it would be to tune that thing?” One thing leads to another, and soon you’re jamming for an iPhone video. This is Clay Shelburn and Zac Stokes performing Stevie Ray Vaughn’s “Pride and Joy” in the toy department at Walmart. -via Metafilter

Many things seem like a good idea as long as you don't actually put much thought into them. These adorable hamster cup accessories certainly fit into that category. After all, hamsters are simply precious and watching one climb into a cup is cute as all heck -but that doesn't mean you want to drink out of a glass adorned with a rodent. If the deeper concept doesn't bother you and you simply must have the cute, they can be yours for a very reasonable $2.50 each -though shipping from Japan can add up quickly.

Andrei Dragunov is a deaf Russian dancer. He dances with his hands, which is called finger tutting. There are elements of sign language here, some even Americans can understand, but the difficulty and the creative fluidity of the movements is what’s really impressive.  -via Boing Boing

Kuma Films calls them the "Dynamic Diabolic Duo." They're a pair of yoyo masters in Taipei who have amazing control over their instruments. The yoyos fly through the air flawlessly, moving exactly where these men want them to.
