Was it being busted by mother/sister/girlfriend wearing her plastic mac?
Being laughed at/teased for wearing plastic rainwear in public?
There must be heads of good stories out there; i'd love to hear them!!
My worst experiences (and there's been a few) would be the time:
1) my sister walked inside my room after a big night out with her friends only to see me wearing my shiny yellow plastic rainsuit. It scarcely helped that I was also tying myself up too.... Her screams brought the house down. Embarrassment factor 10/10

2) I was wearing my shiny yellow rainsuit in Brunswick Street (Melbourne) during a major rainstorm ... all very fine and well until a group of drunks hanging out of a bar facing the street decided to have a go at me despite the fact I was probably the only one who wasn't soaked by the torrential rain! (I'm only relieved they never spotted the latex rubber suit under everything) Embarrassment factor 7/10
