Thank you for reminding me why I vote Republican.

Fucking lost it at :30

What the fuck did I just watch

art, i think

what in the fuck

Happened at :40 for me

Let's play name that drug: Try to decide what each of the 4 people are on.

My guess
Ecstacy
Mushrooms
Acid (paper, very dirty)
Meth (just look at piccalo boy's fingers)

non of the above, most likely just pot alcohol and pills
