I feel like I see a Prius in practically every TV show. On The Office, it looks like Andy traded in his GenII for a new 2010. The new mysterious family on Desperate Housewives has a gorgeous Blue Ribbon 2010. On last weeks Dexter, a Gen II was driven up onto someone's lawn and ran over a bike. Larry David is still driving a Prius. Will he get the GenIII soon? How will they work a Prius into Mad Men?

There are quite some Prius appearances that have not made their way to that site. For example, a G2 Prius was driven by Bruce Willis in Surrogates and actually used in a chase. Another G2 was clearly seen in Knowing with Nicholas Cage. Both are not listed.
