Pull my finger....

I was dating my current wife for a few months and got caught with gas pains and her son was in the room.I knew of I took a step it would come out so I told her to pull my finger and as she put out her hand out her son yelled Nooooooo!!!!!She pulled it anyways.He fell on the floor and was balled up on his side laughing hysterical. She couldn't belive I did that and I told her she turned it loose.It was a long loud one but like I said I had to think quick!
