Brent Spiner, the actor who played Data on Star Trek: The Next Generation, does a really good impersonation of Patrick Stewart, the actor who played Jean-Luc Picard. In fact, it was good enough to fool Stewart's wife on the phone -- at least for a while. Here's a video of Spiner demonstrating this talent at the 2011 Emerald City Comicon. -via reddit
Data got old. The impression is really great!
