What's the funniest or dumbest thing you did?

I just installed a brand new Dynavector Ruby cartridge (23R) on my Alphason tonearm and I was ready to play the first album record using this new cartridge. I was holding the album jacket and could not find the opening in the jacket in order to remove the album. I rotated the jacket to take a closer look, when the album slid out and landed right on top of my new cartridge breaking the cantilever. Remember those album jackets' that had the slit on top, instead of the side where most are?? Upon, reflection, this was not funny, but is sure was dumb. Oh by the way, the album soom made it debut as a frisbie.

I'd been experimenting with homemade p/c's made by a friend of mine who swears by them. I put one on my Classe CDP-1, it worked well at first, then I went on a 2 week vacation. When I returned, the cd player kept shutting off. I would turn it on, it would play for 10 minutes or so, then shut off. I forgot about the p/c. I contacted Classe and they sent me an RA#. To make a long story short, they could find nothing wrong with it. They shipped it back, I've been using the stock cord ever since, no problems. I felt stupid for shipping the unit and waiting a month, when I should have tried to switch the p/c in the first place.

The dumbest thing I did was that I sold my Linn LP-12 with Micro 505S and AKG P8ES 15 years ago. Fortunately, I did not sell my LP collection. I am now just starting to get back to analog again.

I once watched a friend of mine run the outputs of an Aragon 4004MII into the inputs on a Rotel pre-amp. Whenhe turned the amp an it fried the Rotel. I mean flames came out the top of the unit. Now, I know that your all just thinking that that was stupid. Now, for the funny part: he was a custom installer! To this day I always recheck everything he does when I help him out on a job.

I will report only the most recent idiotic thing: I listened to my Genesis 500's, which have their own bass amps driving the 3 woofers per speaker, for 3 weeks with the bass amps turned off. That's right, there was NO bass information coming from these speakers for 3 weeks, yet I didn't notice that the amps had been turned off (possibly by the house cleaner) and instead kept moving my listening chair, turning up the gain control on the back of each speaker, messing with different CDs, etc. Finally, last Sunday night, a light bulb went off and I looked at the back of the speakers again. DUH!!!
The funny thing is, there is a LOT of bass information that comes out of the midrange drivers. The speakers really didn't sound bad at all. An ARC VT-100 Mk III drives the top part of the speakers and really they sound pretty good as minimonitors. I guess I didn't need to spend all that extra $$$ to get full-range speakers after all. I was too ashamed to admit this to anyone, till I saw this thread today.
