I am usually ready before the mrs when we go anywhere so I go start the car and wait for her, then when she goes to open the door I pull away, I continue to do this about 5 or 6 times up the road, sometimes she'll just stand there in a strop so I reverse back to her and she thinks she's won, then I pull away again.
It never ceases to amaze me how much it makes me laugh.
When she says " Pass me that pen " i will always put it in her hand and pull it away laughing. I will always say " Only messing " and do it again until she tries to snatch it voilently then i will say " Don't snatch, its bad manners " and butt her.
