Lost my temper today.

I worked in a Dealership service dept with 14 other techs...you couldn't get any of them to agree on a radio station or if the heat should be on or off etc. I saw two guys standing at the ventilation fan switch, one turned it off, the other turned it on, they went back and forth like that for a minute or two finally the one said "touch it again I'll break your arm..." it was better than watching soap operas or the Three stooges on TV...:)
I would imagine that there was another word or two between ''break your'' and ''arm''.
