The Bachelor (8pm, ABC) - The two-hour finale followed immediately by the first After the Final Rose special at 10pm (there's another one tomorrow night at 10pm). We all pretty much know what's going to happen, we just need to tune in now to watch the train wreck and the tears.
24 (8pm, Fox) - We get two hours of Jack saving the world tonight.
Big Bang Theory (8pm) and How I Met Your Mother (8:30, CBS) - Finally some new episodes on CBS. On HIMYM, the gang suspects Barney (right) has a ... gasp! ... girlfriend.
Also, new episodes of Chuck, Heroes, and The Medium on NBC. The Medium has been strong (and creepy) so far this season.
Late Night with Jimmy Fallon premieres at 12:35am, NBC.
