Phony name Homer Simpson uses to ask moe the bartender for advice in the Season 5 episode "The last Temptation of Homer. Also coincidentally one of moe's tavern's regular customers as well, making it one of the funniest simpson's jokes of all time.
Homer "Moe I need your advice"
Moe "Yeah?"
Homer "See I got this friend named Joey Joe-Joe Junior Shabadoo"
Moe "That's the worst name I've ever heard"
(Joey Joe-Joe Jr. Shabadoo then leaves the bar in tears)
Barney "Hey Joey Joe Joe!"
boy: Hey, shambodo, look at that car!
NO ANSWER.
mom: Tommy, there's nobody there -- who are you talking to.
Demon/shambodo: HA! Made another one look stupid!! He he he...
Homer: Moe, I need your advice. See I've got this friend named Joey Joe-Joe Junior Shabadoo.
Moe: That's the stupidest name I've ever heard.
(A man runs out of the bar crying)
Barney: Hey! Joey Joe Joe!
