Probably 30 years ago I worked on a surgical unit in a hospital that had a cat problem in the basement. Every now and then we had problems with fleas. One morning I was doing a pre-op prep for a back surgery, then was to give the pre-po IM injection. The gentleman was lying in the prone position, looking away from me, and just as I was getting ready to give the injection, a flea jumped right where I was aiming!! Not knowing how to deal with that (I was a fairly new nurse at the time), I reached over and pinched the flea between my thumb and finger. Unfortunately, the gentleman thought I was showing interest!! He turned his head and winked at me!! I was so embarrassed and my co-workers kept it going for months!
