Here's a fun document published by transparency website Public Intelligence: An 84-page handbook the Candian Border Services Agency uses to identify gangs and felons based on their tattoos.

Did you know that clown tattoos are "typical among Latin and Asian gang members" and can have the following meanings:

"Laugh now, cry later"
"Play now, pay later"
"My happy life, my sad life"
"Smile now, cry later."

Download the .pdf, and take it to your nearest tattoo parlor if you want to make those trips across the Canadian border a little more exciting.
