Not In Good Shape

(After a very busy week my girlfriend and I are sitting down to a bottle of wine, the TV is on in the back ground.)

Girlfriend: “Remind me what is a seven-sided shape called?”

Me: “Heptagon.”

Girlfriend: “And a five-sided?”

Me: “Pentagon.”

Girlfriend: “Oh, of course. But what is a three-sided shape?”

(I take a long look to see if she’s trolling me.)

Me: “I think that is your last glass of wine tonight.”

Girlfriend: “What? Oh!”
