Paul Rudd is a perfect anagram of Dr. Lupa Du. Amazing coincidence, right? Not so much: Dr. Lupa Du is Paul Rudd's real name!

He didn't want to hide his heritage and accomplishment completely, so he just rearranged his name to the westernized Paul Rudd. But what else would you expect from the youngest person to ever get a Ph.D. in music theory?
