The Obstacle
George: “I proposed to that girl and would have married her if it hadn’t been for something she said.”
Fred: “What did she say?”
George: “No!”
Changing the Subject
She: “Well! Let us change the subject. I’ve done nothing but talk about myself all evening.”
He: “I’m sure we couldn’t find anything better.”
She: “Very well, then! Suppose you talk about me for a while.”
“I say, Taxi, I’ve only got enough change to pay the exact fare. D’you mind taking a cheque for the tip?”
