When a graduate student, I once shoved a sample into a -80 ºC freezer with a template on the front showing what everything was, written in pencil as an index (everything was stored in a metal rack in a particular position and they all looked identical from the top – it was a bit of a pain to find your sample if you didn't know where to look as you'd have to lift them all out and rummage). Someone had removed something and not removed its name from the index on the door, and I'd placed my sample in its place, let's say into spot H6.
I went around the corner and popped my head into the nearest office – a female (and conventionally attractive) American post-doc I didn't know terribly well was sitting there typing and I just said, "Hey, <name> do you have a rubber I could borrow in a hurry for just a moment? I'll bring it back in less than two minutes, promise!". She changed colour, burst out laughing, and handed me "an eraser"...
