Not the most embarrassing, but one I'm willing to tell:

When in college, a bunch of guys were sitting around one night discussing great bands. I was trying to fit in with everyone. someone mentioned Pink Floyd and I chimed in "I Love Him!! He's great!"

Hahaha!! Needless to say, I was derisively told that it was not a he, but a group! Then summarily made fun of for the next few minutes (seemed like an hour).

Sad thing was, I actually knew they were a group, but was just trying so hard to impress others that I said it wrong. Of course no one believed that and it only made it worse.

Haha. Now just a fond memory, but at the time was quite embarrasing.

Trying too hard almost always backfires!
