Truly Embarassing
A coworker of mine went into Victoria's Secret to buy his future wife a present. He ended up getting her a gift certificate and while he was filling it out, the cashier said to him, "It's ok. You can put his name down there."
That's not the really embarassing part of the story. The truly awful part is that he was dumb enough to tell people it happened. Being that dumb is truly embarassing.
