Two mushrooms walk into a bar.
Bartender says, "We don't serve mushrooms."
First mushroom says, "But I'm a 'fun guy.'"
Bartender says, "Clever homophonous wordplay aside, I said we don't serve mushrooms."
Second mushroom says, "But we're 'fun guys.'"
Bartender says, "'Fun guys?' That's not even a homophone."
