I walk away and go in my house and start bitching. My parents are always like calm down just stay in here a little while. I tell them I have too or I'm gonna beat on whatever vehicle I'm working on with a BFH

 

My favorite is when I slip with the wrench, it hurts like hell, then my first reaction is to punch something, which hurts more.

slip OW **** *PUNCH* OWWWWW FU(K!!!!!!!!!

I almost did that earlier today while changing wheel seals on my wife's mountaineer, but I managed to stop myself before I effed myself up.
