What we're watching: Just making sure everyone is aware, two of our high definition mainstays, My Name is Earl and The Office are doing things a bit differently tonight for their season finales. Instead of slotting a rerun in the place of the now-departed Four Kings, Will & Grace, Earl and Office will all be 40 minutes long, shifting the start time earlier by ten minutes for the latter two. Please adjust your DVRs -- and your lives -- accordingly.

Also ending their season tonight are Smallville, Everybody Hates Chris, Love Inc., Eve and Cuts.

Our traditional high-def listings continue below.
