Back in the Good Old Days, when Dudley Fudpucker was whooping it
up in college, he was standing at a bar one evening, when a lady
of enticing appearance approached him and suggested that they
have a drink.
Dudley said, "Well, I'm no John D. Rockefeller, but I'll buy."
After developing a slight buzz, she suggested a dance.
Dudley smiled and said, "I'm no Fred Astaire, but I'll give it a
whirl."  Later, she suggested that they go up to her room.
"I'm no Cary Grant," replied Dudley, "but I'll follow you up
there."
They leave and go to the lady's apartment. They have another
drink, then do what had been on their minds all evening, anyway.
Afterward, the lady says, "What about some money?"
Dudley shot back, "Well, I'm no gigolo, but I'll take it!"
