Jock itch spray damn near killed me one time.
What, were you holding it in front of a cigar while spraying it on??
True story; going through security in the Atlanta airport; I had a can in my bag and didn't declare it. They flagged the bag, searched it, and the TSA woman held it up and yelled "who's this? Anybody?" waving the can around. She had my bag, so I couldn't just leave, but I was like "Thanks SO much for your discretion."
