Outgoing Microsoft CEO Steve Ballmer is well-known for his on-stage antics during keynotes and product launches but did you know he once starred alongside co-founder Bill Gates in an Austin Powers-themed short? Or that the duo once filmed a spoof of the Night at the Roxbury? Maybe you missed the Budweiser-inspired Wazzup play day video they filmed for the PDC 2001 keynote?

As the gang at The Verge points out, the two have been featured in a number of short videos filmed for Microsoft over the years. My favorite is probably the aforementioned play day video followed closely by the Roxbury bit. How about you – what’s your favorite Bill and Steve moment?
