Saturday Night Live episodes? I'm Carol!?

Anybody know where I can find some snl episodes? I have some in perticular. Lance Armstrong/Sheryl Crow 10, 29, 2005. Alec Baldwin/Shakira 12, 10, 2005. And Peter Sarsgaard/The Strokes 1, 21, 2006. They're all from the 05-06 season and I pretty much just want it for the "I'm Carol!" skits. That was my favorite but I can't find it anywhere. If you could tell me where I could buy it other than online that would be great. I found it on amazon.com but I don't buy things online. THANKS IN ADVANCE!!!
