Thanks to commenter yarbles, we were alerted to evidence of two more members of the PayPal Mafia posing, like YouTube founder Jawed Karim, in mafioso costumes. Pictured, above, Yelp cofounders Russell Simmons and Jeremy Stoppelman. (Stoppelman's the one with the fake mustache. At least, we hope it's fake.) Any more evidence out there? Join the gang.
