Collegiate comedy favorite Dane Cook has been royally ripped off….by his BROTHER. TMZ reported yesterday that Dane’s business manager/brother has been arrested for stealing millions of dollars from his famous sibling.

Darryl McCauley — who was in charge of Cook’s financial affairs since the 90s — was arrested today by the Massachusetts State Police and charged with three counts of larceny and forgery. Authorities say in one case, Dane’s bro forged a $3 million check and deposited it in his account. McCauley will be arraigned tomorrow in Woburn District Court.

Maybe he just got sick of watching his overrated brother get the money and the girls. I really can’t blame the dude.
