For me, amusingly enough, my most embarrassing moment actually had to do with a clam. We were in UBRS (back when UBRS was still hard and let you run 15-man groups) and one of our warriors got Rohan Gold bugged while looting. While it's fun to watch someone scoot around in the looting position, it's not too good when it's your main tank. At the time the only real way to get out of the glitch was to carry a clam with you, open it and close it without looting. Being the only female in the raid - and not even thinking about it first - I cheerfully offered to give our main tank the clam I carried with me since he was grumping about being stuck.
