The stupidest thing I have ever done...

Hell just the other day pulling my transmission for a converter swap I pulled the dipstick tube out without draining the fluid first!!! ain't no going back after that. Look like someone was murdered under there.
I put many qts into a dry C4 without the thing running. After 5, the stuff started coming out the vent on top and onto the polished cement floor. I didnt notice and kept pouring it in until the expanding puddle started coming out from under the car. By that time the puddle was 7 feet wide. Took me 3 hours and 4 bags of kitty litter to clean that mess up.
