Other improbable things that my students have recognized

• The Numa-numa song
• The Ranma 1/2 theme song (hey, it IS over 20 years old...)
• Hannah Montana
• The PowerPuff Girls (wait, wait, there's a Japanese version of them now)
• Marie, from "The Aristocats" (the character is VERY popular in Japan -- My boss is a big fan

On the other hand, one of my elementary students from back when I was teaching in America recognized Genma Saotome (in panda form).

On the gripping hand, some of those same students at Prosperity Heights asked me in all seriousness if they had Nintendo or PlayStation in Japan. (My response: Show the videotape of the first episode of ポケットモンスター.)

(apologies in advance for the ultra-geeky reference there...)
