I used to have a friend as a kid that liked to read comic books from back to front.

Was his name Mr. Mxyzptlk?

 I didn't  know that Mr. Mxyzptlk was a thing.

The mischievous magical mite with a mouthful of a name, Mr. Mxyzptlk (pronounced Mix-yez-pitelick) first pestered the Man of Steel in Superman vol. 1 #30 (1944)
