Maybe I'm imagining it, but it seems like every time Olbermann says anything, Collinsworth replies snidely/angrily (thinly disguised as "jokingly." We've all done that, right? We have a really annoying aquaintance, everything they say just cheeses us off, but it's not socially acceptable to call them an idiot to their face, so you pretend to inject humor into . . . calling them an idiot).
Also, I'm 75% sure that when Costas threw it over to "Olber-time," Collinsworth actually sneered. Sneered.
So, has anybody else noticed this? If not, keep your eyes open, and maybe you will.
