I don't know if these have been mentioned before, but how about "Mama Mia, that's one spicy meatball", and "I'm a Pepper, your a Pepper, wouldn't you like to be a Pepper, too." I believe Texaco had "Take you car to the man behind the star." Some more--"There's something about an aqua velva man", "Plop, plop, fizz, fizz, oh, what a relief it is", and who could forget "It helps the hurt stop hurting".
