I have found that acting like a coward can be hilarious.
You know when someone cuts you up on the road and you get mad and he gives you the finger, so you tell him to pull over and instead he drives away like a bitch and you're left fuming? I do that now.
"Who's this cowardly piece of shit posting signs up? Fuck, I'm gonna smash him! Grrrr!"
You: "Tee hee hee"
