I watched the Osbournes the first season ("anyone want a burrito?") but haven't caught any of the second. I really loved "The Surreal Life". Boy did my opinion change about Corey Feldman. I use to think he was so cool but after that episode....
One reality show I have a morbid fascination to watch but haven't caught yet is the new show on Comedy Central, "I'm with Busey." The previews made me laugh my ass off.
