Okay, CBS has posted a couple of new CSI related videos on YouTube.
The first one is an actual clip from the premiere episode. It's only about two minutes but it's pretty suspenseful. If it's any indication of the rest of the episode, it'll be a nail biter.
The other video is much lighter and funny. It's about a "new show" featuring the three male leads, Grissom, Horatio, and Mac, in a situational comedy. Don't want to give away the "plot" so watch and find out for yourself. :P
