The IT Crowd has been on Netflix for at least 6 years now. I've seen it so many times it's nearly memorized, but there are always things I hadn't noticed before in their office. What caught me most recently was a Robert Pollard poster from a show in Southgate, MI. Pollard is the lead singer of Guided by Voices, a band Maurice Moss and Gentle Irish Roy are known to enjoy.
The Robot's Voice has this top 10 list, for example.
I had the chance to see Pollard and GBV at a club in Kalamazoo called The Nouveau Room in the 90s--don't look for it; it's not there anymore. He was very drunk, and ruined a lot of the songs.
Their latest video stars Rob Corddry and Matt Jones.
