Get the willie lump lumpmug. 
This is a man who says "Oh my god" and "You're kiddin' me" a lot. He dances like Carlton, mostly to the song "Apache" by Sugar Hill Gang. He eats excessive amounts of White Castles and irons his underwear and socks every day.
"Oh my god, I'm a regular willy lump lump. I can't wait to go to White Castle today, right after I finish ironing these tidy whiteys. I hope I hear "Tonto, jump on it" in the car on the way there!"
