oh my gosh.

Ernie: [on the phone] Syke's Whale Wash! You get a whale of a wash and the price... eh... is really, really low, considering how good the wash is. 
Sykes: It's "oh my gosh!" "You get a whale of a wash, and the price, oh my gosh!" 
Ernie: Got it! 
[the phone rings, and Ernie answers it] 
Ernie: Whale wash! 
Bernie: Rhymes with gosh! 
[both laugh] Sykes: [chasing the brothers off] Get out of here, you two! Go be useless someplace else!
