It pisses me off when it's just 4:00 - 5:00, but for me 5:00 - 6:00 is great because that's when I get home from work, get a snack, and turn on the TV (I work the night shift).
Comedy Central used to show it at like 7:00 am - 9:00 am, and that was great for me too because I would just put it on and fall asleep to it. It hasn't been in their line up in forever. They recently put it on a little bit for some holiday/date/event/whatever (I don't remember what), so they do still have it, but they choose not to show it at all. Both channels have the rights to it, and both channels are squandering it.
