A man is sitting on his front step staring morosely at the ground when his neighbour strolls over.
The neighbour tries to start a conversation several times, but the older man barely responds.
Finally, the neighbour asks what the problem is.
"Well," the man says, "I ran afoul of one of those questions women ask. Now I’m in the doghouse."
"What was the question?" the neighbour asks.
"My wife asked me if I would still love her when she was old, fat and ugly."
"That’s easy," says the neighbour. "You just say, ‘Of course I will.’"
"Yeah," says the other man, "that’s what I meant to say. But what came out was, ‘Of course I do.’"
