Is it normal that i enjoy throwing dog logs at cars?

You should try your own logs!

Wait till summer when you can squeeze them through people's open car windows

Heh. When I was a mere lad, we used to chase little girls with dog logs stabbed on the end of a long stick. Shit-on-a-stick as it were. Highly gratifying.

You are a very sad person who seems to enjoy causing discomfort to other people.
Something seems to be bothering you. Although I did enjoy putting dog poo in a paper bag, putting it on someones porch lighting it on fire and knocking on the door and running away.
They would run out and stamp the fire out. Thought it was hilarious. Just make sure someone is home
