Discovery Channel/Animal Planet

I am sick and tired of watching the Discovery channel and Animal Planet. Dave watches these channels on a daily basis. I can't take it anymore. I'm going to go crazy. We just got done watching a 2 hour program on Cicadas. As much fun as that sounds-it's NOT. I feel like putting a parental block on these channels so Dave can't get to them. Hmm, sounds like a good idea.
