You know you're overtired when...

Based on recent events, I have compiled a top-ten list of how to tell if you are overtired.

You know you're overtired when...
1. You forget to take your contacts out before going to sleep for the night.
2. Your roommate tells you things you said the night before when you were awake, but you have no idea what she is talking about the next day.
3. Sleeping in means waking up at 6:30 AM.
4. You portray bi-polar systems (more frequently than normal, anyway).
5. Everything suddenly becomes hysterically funny. And I mean everything!
6. You sleep talk at night.
7. You drop your super heavy backpack crammed to its fullest on your foot.
8. You wear your shorts backwards for most of the day...accidentally of course!
9. Your personality suddenly changes.
10. Your friends compare your actions to those of Mr. Bean.
