You're all grown up. You can drive, you have credit cards, you've been to family members' funerals. You're 22 going on 23, you've been through 16 years of school, you have a bachelor's degree, and now you want more, so you go to graduate school.

Then, you're sitting in an 8 o'clock class, dead silent except for the teacher and someone farts out loud. Suddenly, you're 5 years old again. You try, but you can't hold back the laughs, and listening to your buddy sitting right next to you trying to do the same isn't helping at all.

Do we ever really grow up?
