You're blocking the entire crosswalk, asshat.

The idea is simple. Here's the COLOR PDF and GRAYSCALE PDF. 

Be your own Willy Wonka in the magical world of crap parking. Print some out and keep them handy in your car. When that special occasion comes where you just have to absolutely commend someone's outrageously horrible parking effort, you get to reward them by sticking one of these babies underneath their wipers. 

Yay for being snarky and passive-aggressive!
