Reminds me of the old Woody Allen sthick:
Inept bank robber Virgil Starkwell hands a hastily-scrawled holdup note to the teller. Baffled, she reads it aloud:
“Please put $50,000 into this bag and abt natural, because I am pointing a gub at you.”
“That’s ‘gun’. I’m pointing a ‘gun’ at you.”
“No, no, that’s definitely a ‘b’.”
What about that scene from Take the Money and Run where's he's in the prison courtyard holding on to a gun he made from a bar of soap, and all the other prisoners are laughing their *sses off from their cells because the break was called off. Apparently, everybody knew but him.
