I know it's ESPN, which I've been hesitant to read but this is just too funny to pass up. Mike Leach duped Texas defensive staff with a fake laminated offensive call chart that was "mistakenly dropped" on the field. Decades later, information is still sought by both sides that were involved lol. 

The 1999 Texas staff had a young Tom Herman and Everett Withers as assistants, which made this even more interesting.
