The satisfaction of using the restroom after holding it for a long time.

Making a perfect bag of popcorn - none burned, no kernels, all popped.

Making a witty comment that draws a lot of laughs and even surprises you.

Hearing a stranger fart, and watching them look around to see if anyone heard it.

Watching someone pick their nose, and then watching them look both ways like they got away with it.

The way an airplane toilet flushes and surprises you.

When your spin instructor says funny motivational things like, "It's not about speed; it's about POWER!"

When you're trying to be serious, but you accidently smile.

Laughing at your own texts before you send them.

That 'freshly applied deoderant' scent.

Watching a baby or a dog sneeze.

That hilarious, awkward moment when everyone else has stopped laughing, but you simply can’t stop.

Trying to act sober when you're not.

When you get really into doing your homework.

A friend in class makes you laugh, you get in trouble from the teacher and you cant look at you're friend again cause you have uncontrollable laughter.

Self-mockery. Laughing your butt off because you did something extremely stupid. Awesome!

Getting a phone update and it ACTUALLY makes the phone work better.
