Heights and a figment of my imagination called the stingpig.
It had a warthogs face, the body of an accordion and shot acid out of its nostrils.
I thought him up to fill the sound of a dieing cow. (Obviously didn't know it at the time)
(edit): Oh and the car wash. i don't even remember why
Played Simpsons hit and run zombie level, when the guy said he was getting his brains eaten on TV, I couldn't fall asleep until 3 am every morning.
