Dumbest bike "fix"

What's the dumbest, facepalm-inducing thing you've ever done in attempt to fix a bicycle, or just anything else related to cycling? This was prompted by the guy who somehow got an entire bottle of glue in his bike. I'll go first.

So, I would call my try more "ambitious" and "poorly informed" than truly stupid. Was trying to fix GF's creaky BB. I wanted to do the work myself, and get a BB online. Of course, she had the cursed ISIS crank interface, and I only had the standard puller. I tried a technique I'd read about on the interwebs: using coins to make the puller bottom out faster (yeah, yeah always use the proper tool...)

Things were great, until the handle was turning very easily, but the cranks weren't moving. Of course, the puller went straight through the penny. So I thought I'd stack a couple and try again. Same result. In the wee hours of the morning, I start to get careless and destructive. Finally, I'd stuffed a half hour's worth of parking in there and stripped the crank threads (I'd finally decided that even destructive removal was ok, as I wanted to replace the garbage cranks for her anyway). Nothing budged, and I paid extra labor to have the stripped cranks removed at my LBS.

Not that bad, just ended up costing me more than it should have.

Despite looking at the markings specifically to avoid such a mishap, I managed to get two different unicycles assembled with the cranks reversed, which makes the pedals loosen themselves until they strip out.

But my all time favorite was on a car, not a bike or unicycle. The lights on my dash burned out one by one until the whole dashboard was dark. Which meant I could not see the speedomer at night, so I couldn't tell how fast I was going. So I tore into the dashboard, and got all those lights replaced. Only, in the process, I damaged the speedometer where it didn't work. But at least I could see it not working when I got through.

These aren't my work, but they're worthy of FacePalm:

^stripped pedal hole? No problem. We'll just drill a hole through the crank & pedal, put a nail through it, and bend it over. There, that was easy.

^Schrader valve won't fit through a Presta valve hole in the rim? Ok fine. It's easier to reach the valve this way anyhow. (her front wheel had duct tape wrapped all the way around the tire and rim, including across the brake track, to keep the valve from slapping on the fork)

I can't really remember anything that bad I've done. Although I did make a temporary fixed gear by throwing a wheel with a rusted freewheel on a Huffy. Didn't last long...
