What's the funniest or dumbest thing you did?

I've got a good one.
At the age of seventeen I'm at home my parents go on vacation to Florida. I decide to put a new sound system in my VW Beetle. I'm drilling parts in the basement. I reach up and un plug a cord from the closest socket. Finish my drilling and leave forgetting to insert the plug back into the socket.

Two weeks later my parents come home. I had unplugged the big deep freezer. My dad had just split a whole cow with his buddy and it was in the freezer. Man did that shit stink. Took me five hours of gagging and hurling to get that sucker clean.

My dad was so pissed. Gotta have those tunes

Speaking of Dads, when I was sixteen back in 1977 I bought my first integrated amp, a JVC 30 watter as I recall, and tried hooking it up to try it out after school on my dad's Pioneer Project 60's (anyone remember them?) Oh, er, I forgot to disconnect the wires to HIS receiver (a Webcor) and used one of his outputs from the tuner input into my JVC. I turned it on and fried the output section of his receiver. When he came home and I had to tell him I destroyed his Webcor, well, it was not pretty!

A friend of mine plugged his vacuum cleaner into his PS Audio P300 power plant... heh heh heh heh. The thing totally shut down and would not reset. Luckilly, he only blew the fuse on it.

I had just gotten my M-300 back from Audio Research after weeks of no music. I was so anxious to hear it, I brought it in the house during a rainstorm (uncovered) and promptly plugged it in. Smoke, sparks, and back to ARC for 2 more weeks of no music.

It was my pleasure, Gunbei.I took great satisfaction with this gift.I also appreciate your kind return gift of the Monster Cable Power strip. It is working very nicely in my bedroom home theatre set-up. As far as dumb things I've done,I'll let you all know later, because there are too many instances and I need to think and choose the dumbest.
