All you need to know for a cop encounter:

The eyes are red because you have allergies.

The breath smells like weed because you've been eating cannabis-flavored lollipops--I'm tryin' ta get off th' stuff, mister! It's ruined my life, it has!

You're laughing so much because of something behind the officer--when he turns around, tear ass.

You have weed in your hand because--at this point you punch him in the face.
