An ______ and a ______ are taking a piss in the bathroom. The ______ sees the ______ walking out without washing his hands and says to him, "Hey didn't they teach you to wash your hands in the ________?"
The _______, smiles and replies,"No. They taught us not to pee on our hands."
I have found it helpful to do the stretching exercises my physical therapist recommends. Do some core strengthening exercises, such as the ones highlighted at The Mayo Clinic. By keeping your core strong, your back won't put itself in a position to cause that sciatica pain you are having.
