I was putting something together in the lab today and dropped a screw. I never heard the "tick" of it hitting the floor, and after a few minutes of searching, I found it in the cuff of my pants:
I guess that should tell me not to assemble things while wearing dress pants.
I used to work with liquid nitrogen. This stuff is almost always boiling (though it's extremely cold) so it splashes all over the place. One day I was wearing loafers, the kind with the stitched lip around the edge of the toe, and I looked down to see a puddle of gently bubbling LN2 on the top of my shoe. Hmm.
