Not my most embarrassing moment but I did pull a blusher (though I didn't) in Werewolf Junior 1.
Fea, the ranger, & I, the seer, had a nice ruse going in which Fea was the "seer" & had "dreamed" that I was the "ranger." The wolves didn't suspect me of being the seer at all & Fea was set to protect me night four (I believe) before I forgot that Fea had "dreamed" of me & brought up the possibility that I was not the ranger.

This caused Fea to become suspicious of me & not protect me, causing me to be brutally slain by the wolves that NIGHT.
Fortunately, the remaining villagers puzzled things out on their own & defeated the wolves, otherwise my blunder would be even harder to live down.
