Oh my gosh! These are cracking me up, guys. haha.
It's kind of crazy because I have SO many embarrassing moments, but I can't think of any of them right now! I'll have to get back to you on this subject...
EDIT:
OK I just thought of one.
When I was in 7th grade, my science class had a pet hamster named Turtle (the boys named it.

). So after a couple months, he died. and the day he died for most of the day I was like "Oh my God! I can't believe Turtle died, etc." Then at lunch, I had just stopped talking about him. One of my friends comes up and she's like "Did you hear that Turtle died?" and I had a MAJOR brain fart and I was like "...who is Turtle?" It was soo funny at the time.
