Oh crap, I've done so many dumb things, and still counting.
Going down a little one lane dirt road near my mom's one night in my little orange VW bug. Came across a cow lying with it's head turned in the middle of the road.
Honked and it moved it's tail, so I got right up to it and hit the horn again about 3 times.
"The cow" turned it's head & stood up. Biggest fucking bull I ever set eyes on.
Those little VW's can really haul ass in reverse with the proper motivation.
