The first half of this video features a guy singing a song in reverse. He’s also doing some stuff that will look strange backwards. The second half is where you find out what song he is singing, when the video goes backwards! This performance must have taken a lot of practice. -via Boing Boing
In a phonetics class I took in college:
The professor recorded herself saying something like
"Mal atTILLa da HE rem", then played it backwards and it became "Marry had a little lamb."
We also had to learn how to transcribe and say our names backward, so when it recording reversed it sounded like our names.
