Us folks in Washington state might be more familiar with it than a lot of Americans, as a local company makes a version of the treat under the name Aplets and Cotlets.

A classic Far Side comic had a group of triumphant hooting cavemen carrying an enormous carrot through a jungle, with the caption "Early vegetarians returning from the kill".

The Cocoanuts is technically the Marx's second film; they made a silent short called Humor Risk, which is now lost (one story is that Groucho himself hated the film so much he burned the negative.) There aren't too many details now about it, but they evidently didn't play their familiar characters.

I wouldn't be surprised if a lot of people out there are still using dial-up; ISPs aren't going to string high-speed cable out into the boonies.

A couple from pre-Internet days that I've always enjoyed:
"How can you just lie there and accept Continental Drift?" -Charles Addams
"How can you sleep knowing full well there are communists in the French government?!" -Bloom County

"Move along! Nothing to see here! Please disperse!"

As the video says, it was Ellison's Outer Limits script "Soldier" that Ellison claimed was ripped off, not Must Scream. Cameron has always denied that he got the idea from Ellison, and it was the studio who settled and put the credit in the film.

It is one of his funnier ones, but it's a repeat, which I wish he would just stop doing.

Kenny Rogers is another that switched genres; he started out singing rock songs before switching to country. One of them was memorably used in the Coen Brothers film The Big Lebowski.

He did make a brief appearance in the 50th Anniversary comedy special that Doctor #5 Peter Davison put together, The Five(ish) Doctors Reboot. If you're a fan of the show, the whole thing is hilarious and well worth watching.

Rankin/Bass did a rather longer animated version for TV that is pretty faithful to the book, and even used Tolkien's lyrics for writing up the songs. (The main title theme is a rather sad exception.) Worth checking out if you're a fan.

"..and another for Jenny and the wimp!"

One I've heard: In one scene where Bowie has young Toby Froud sitting on his lap, he's keeping Froud distracted by jiggling a toy in his out-of-shot hand.

The folks at blambot.com also offer a few Lovecraftish fonts. Yes, it's a commercial site, but the fonts in question can all be downloaded for free.
