A couple things I have discovered to be extremely useful:
- Swearing. Unheard of before combinations are a plus.
- Tool throwing. The more expensive and precious the tool the better. It also helps if you throw it in the general direction of a window or your garage TV. It also counts if you drop the tools in the oil pan.
- Dog kicking. Your neighbor's annoying yap-machine, go and kick it in the ass. Kick the neighbor too, while you're at it. And screw his wife.
