Overheard non sequitur

I was only paying attention for a second but the sentence that I heard was said forcefully. One guy said to the other " What the hell do you know about Bob Sagat anyway?". This pretty much made my day. I'll bet that this comment was "shoot milk out of nose" hilarious even in context. What could they have been talking about? Whatever it was they were both very passionate about Bob Sagat. I'm glad I left the house today.
