A few years ago, my sister, who has a pretty twisted sense of humour, emailed out this picture because she thought it was hilarious:
A few days later, we all had to go to Dads for dinner and I showed up without my girlfriend. I was sitting in the living room with my sis and she asks me where the woman was and I told her that she had scheduled something else that night because I had told her that this dinner was the next night.
My sister replies "oh, that sucks... You know what you should do?"
I say "sure. Next time I'll just punch her in the face to prove that I'm right" and we kill ourselves laughing for a second until we realized that our aunt (the pastor's wife) had entered the room and was frozen in a mid sit-down manouvre, eyes bulging, just staring at us.
I had to go into damage control mode and assure her that I'd never hit a woman, meanwhile my sister is chiming in with things like "yeah, unless he was right"... I don't know if you had to be there to find that story funny, but we still laugh about it to this day.
