What's the funniest or dumbest thing you did?

Another one! Sold my turntable on Audiogon. Went through great lenght to find and pack the sucker (Thorens 166 mkII). It was a good sale, the table was tweaked, AQ Mat, Ortofon MC ctg, new feet etc...good for several hundreds. On the way to UPS, i was to put the box in the trunk/hatchback of my Mustang. I got the phone call, my wife went out to call me. I cut the conversation short (tele-marketeer) and went back into the car. Turned the key, placed in reverse and ran over something....!!! You can guess the rest!

I had a CD Player with volume control but wanted to integrate it with other sources so needed switching and volume control. Built a passive box with remote controlled switching via top quality relays and a motorised volume pot, bypassing the volume for the CD player. I didn't put any security code on the remote and the sun managed to trick the volume to go up to full, while switched to a radio station, while I was out for some hours. My speakers were totally blown into next week - wires poking through the cones, all caps blown on the crossover - only the cabinets were recoverable. It must have been incredibly loud. And I thought I was saving myself money by not buying a top preamp - quite the reverse.

The absolute dumbest thing was setting the speakers on the window sill of a 2 story apartment so it could be heard outside. Fourth of July party, playing some patriotic music loud when crash, no not a cymbal but one of the speakers falling 16' to the sidewalk below.

Ive never done anything stupid (knock on wood), but my friends dad who got me into hifi punched a hole in the surround of the woofer in his speaker while commenting that it was amazing that hes never had to refoam them yet.

I was in a hurry to put a new NYAL Moscode 300 Maxi into my system. All of this shuffling combined with living in hot Arizona worked up a sweat pretty quickly. As I was plugging in and turning on the Moscode a single drop of sweat rolled off my forehead and fell through the vent slots onto the board and POP, CRACKLE, SNAP. I dove to shut it off and it was too late! I took out one side of the amp!
