Dane Cook: No Brotherly Love

You know that saying 'business and friends don't mix'? Try adding family as well!

Dane Cook's brother was arrested on Tuesday in Massachussetts for allegedly stealing millions from his funny man sibling. TMZ is reporting that Darryl McCauley--who worked as Cook's business manager-- reportedly forged a $3 million check and deposited it in his account.

McCauley had been handling Cook's financial affairs since the 1990s.
