"He's reliable. He's considerate. He's like your exact opposite."
"So he's Bizarro Jerry."
"Bizarro Jerry?"
"Yeah, like Bizarro Superman, Superman's exact opposite, who lives in the backwards Bizarro world. Up is down, down is up, he says hello when he leaves, goodbye when he arrives."
"Shouldn't he say badbye? Isn't that the opposite of goodbye?"
"No, it's still goodbye."
"Does he live underwater?"
"No."
"Is he black?"
"Look, just forget the whole thing."
