I do this every so often because it's kind of a game to me to see how long I can keep it up till the person catches on.
I repeat the last word the person says in question form.
Example:
"Hey, me and Jenny are headed to Jim's Pizza Hut."
"Jim's Pizza Hut?"
"Yeah, you know the one on F street."
"F Street?"
Over there near the harbor with the big carousel."
"Carousel?"
"Yeah, you know the one you went with me and Jane."
"Jane?"
"My girlfriend."
"Girlfriend?"
"Ok, what the f**k is wrong with you?"
Once they call you out and have caught on the game ends. I've carried on a conversation over an hour once doing this. It's really awesome when the person you are doing it to has gone through this a few times with you.
My daughter has gotten me a few times herself and she'll laugh on and off for the day at my expense. Her husband has called me an a*s for teaching this to her a few times too.
