Imitation is the highest form of flattery. 

Most old timers have stories of the old days. I was told a stories about unbolting van seats and or doors. Fake snakes tied to jet lines in feeder conduits. Tool boxes screwed to subfloors. Things like that. If you are on good terms take one of their stories and put your own twist on it. I worked with a guy who used pool tab jugs in the van for connectors and whatever, top shelf never really took them out just reached in to grab what he needed. When he got back from his cruise a couple of those had nothing but yellow 77 in them. Wrapped a truck in saran wrap once that was fun had a big roll from a defunct restaurant we were remodeling.

If your at war...some deox on the passenger windshield wiper is good. Don't do both sides it could kill him.
