What should you set your TiVo for tonight? And what should you say Ti-NO to?

Our staff combs through this evening's television listings and helps readers set their viewing schedules:

• 8 p.m. Let's hope there are more booms than busts on American Idol (Fox); A shady sergeant is killed on NCIS (CBS).
• 9:00 p.m. Scrubs meets Sesame Street (ABC); Seriously gruesome deaths on Fringe (Fox).
• 9:30 p.m. Will Cox become the Chief of Medicine on another all-new episode of Scrubs (ABC)?
• 10 p.m. Elena confronts her past on Without a Trace (CBS).

Sorry, it's a rerun of Privileged tonight.
