"Oh look, a picture of a horse!"
"...Let's just add a horn on here..."
"...Make some copies and paste them in a tin can..."
"...Paint in some blood..."
"...and there you go. Instant idiot fodder."
If a picture looks incredible, check the source. If it came from crazyfacts.com or lookaconspiracytheory.biz, there's a good chance it's crap. Please, Please, PLEASE stop believing every stupid thing you see. Do yourself a favor and fact check first. Thanks.
