Penrose, Colorado

Tiny town that's boring as fuck. Population? Counting sheep, goats, horses, donkeys, cows, chickens, camels, cats, dogs, mice, rats, snakes, buffalo, mountain lions, deer, coyotes, and jack rabbits... There are too many to put. The only way you'll get a piece of ass, is if it's a donkey. (There are donkeys everywhere..) Full of hick farmers who LOVE sheep. We've got a watered down version of every clique that ever existed. Jocks, Emo's, Skaters, Preps, Gangstas, etc. Everybody knows everyone...so watch who you sleep with!

Trailer trash is the upper class.

We made it out alive. Hope you can do the same..

Visitor to Penrose, Colorado - "Let's go to the park!"
Resident - "No..it fucking sucks.. We only have one park. And they took away our merry-go-round.."
Visitor - "What pricks!"
Resident - "Fuck the government.."

Example 2:
Resident - "No..wait! The one fun time around here.............."
-five minutes later- "......we don't have fun times here.."

Penrose Triangle 

A mind blasting object that is made out of pure impossibility and under suspicion to be created by Satan.
Often used by math teachers to show 'How cool math can be'.
Also referred to as:
'Penrose tribar'
'Penrose crap'
'But this side goes below that bar and...wait, what?'
'F*CK-THIS-THIS-STUFF-IS-IMPOSSIBLE-angle'

Because it generates so much frustration if tried to comprehend it is also the main reason for suicides of kids under the age of 12 ( Just above Spinach ).

When I tried to re-build the Penrose triangle it vaporized my braincells to tiny bits!
