My mandatory random comment:
My personal trainer had a habit of helping me get up from certain positions, like lying on a weight bench. One day, he proffered his arm to me, and I bit it ... not breaking the skin, more of a pussy cat "Stop that!" kinda bite. Scared the hell out of him, but we both laughed.
Same guy that once offered to pick me up off the floor, after I missed the bench. He gave me his arms. i thought he was anchored. I pulled, and he went ass-over-teakettle over me.
The other three people in the room thought it was hilarious.
