Monday night is CBS night at our house. Are there other networks with shows on that night? I wouldn't know...
Tuesday: NCIS (CBS), then House (FOX), and back to Cane (CBS).
Wednesday: Was Back to You (Fox), now it's Pushing Daisies (ABC) and Private Practice (ABC), then South Park and Sarah Silverman (Comedy Central).
Thursday: Must See TV on NBC: My Name is Earl, 30 Rock, The Office, Scrubs (because it's there), then ER to finish off. ER Jumped the Shark, circled around, and jumped it three more times to make sure, but it's like a train wreck; we can't stop watching it...
Friday: We used to watch Numbers (CBS), but I haven't caught any episodes this year. Star Gate Atlantis is pretty much the "must see" for Fridays.
