I'm just so shocked that no one has mentioned Cher's "Believe"...
(kidding)
I'd go with the "tried and true" LL Cool J's "Mama Said Knock You Out" (don't call it a comeback, I bin here fo' years, rockin' mah peers an' puttin' suckas in fear)...
...or Carl Douglas' "Kung Fu Fighting".
"Everybody was kung-fu fightin'. Those kids were fast as lighting. There was funky Chinamen...from funky Chinatown."
