Got some new tubes to get my old 27" steel road bike up and running. The tire was seating funny, like it was too big for the rim now. I re-seated it once and everything looked good. Moved on to adjusting the front brakes when I very faintly heard squeaking rubber. As soon as I realized the trouble I was in for, the tube blew up in my face (the bead came out of the rim). My reaction was to immediately get up and walk to the next room, as if I could walk it off, or maybe to help me contemplate my new life as a deaf guy. When the shock faded I realized I wasn't bleeding out the ears, and eventually my hearing returned good as new. Now I'm just ignoring the fact that my ears may be slightly aching.
Gotta figure out what I want to do with that bike. It's too big, possibly even heavier than my Surly 29er, and I ran into a car on it a few years back and the front end has been slightly wonky since (yet that same tire and tube have been on it ever since).
