Woo Hoo!

Woo Hoo is one of Homer's catchphrases, most commonly used when he is happy. In "The President Wore Pearls", he is seen going "doh! doh! doh! woo-hoo! doh! doh! doh! doh! doh! doh! woo-hoo!" when a wheel is spinning round and he says Woo-hoo when it gets to 17, his number. In "Mayored to the Mob", he says it, but when Marge protests, he says "I said woo hoo," in the same tone.
