Cleo - check out Opie & Anthony - channel 202 (I think it comes with the free trial) It's very addictive
Anthony's playing the the celebrity World Poker Tour starting tomorrow, so they won't be on live until 3 PM EST - which means they'll probably run "Worst Of O & A" all morning & that'll give you a good sample of past shows
Commercials? HA! I'd bet there's 6 minutes of "breaks" every hour & they commercials are mostly for other XM things mixed in with comedy bits.
