Wedgie

So I'm in the bathroom with my 4 year old. Trying to brush his teeth. He is on the floor rattling off a story to me. I'm multi-tasking, you know, picking up a bit, wiping the counter down, bending over to put something under the sink.
I stand up and start to reach around to pull the shorts which seem to have found their way up my butt at some point during my multi-tasking efforts out and mid-sentence he reaches up, grabs my shorts, tugs them out of my buttcrack and continues on with his saga.
Me: What did you just do?
Him: I was pulling your shorts (giggles start) our of your BUM!
