Lets see...what other stupid things have i done...
pulled the engine out of the 66 stang with the trans attached...didn't drain the trans fluid and left the yoke out. Pretty quick way to turn the garage floor into a skating rink
Cooked painted parts in the house oven
Used muratic acid to clean a tank...and then dumped it out in the back of the yard. Grass hasn't grown there for 2 years
Removed the carbs off the 76 GL1000, freshly drained gas, went to tack weld a float post and WHOOF...a big fireball in the garage as soon as the arc was struck
Fixing an old 2stroke snowmobile. Pulled the throttle lift so i could spray carb cleaner in it and let it soak for a couple days. Did that for 3 days and thought "i should turn the motor over to make sure the engine is free" and pulled the start rope with all my might...with the kill switch in the "ON" position...that sucker cranked up, WIDE open, and took off across the field with me still attached by one arm to the handle bar. It was a fun ride till it hit the fence...
Told this one girlfriend of mine she was "filling out a little bit"...
