'Pretzel Mary'
"Car 54, Where Are You?" was one of the few shows that could make me laugh out loud. I laughed the loudest at the "Pretzel Mary" episode. Pretzel Mary was a mean, ragged old lady who made a living selling stale pretzels to passers-by in Central Park. She would try to cajole them into buying one of her unpalatable pretzels. When they did, she would coo, "Bless you, sir (or madam,) bless you." When they didn't, she would scream, "Aah, ya cheap bum!"
It turned out that Pretzel Mary was actually an extraordinarily rich woman who hid all the cash from her pretzel sales under her mattress in her Greenwich Village hovel.
