celebreality shows in general.  .  I liked “Celebrity Fit Club”, and I’m really looking forward to “Armed and Famous” (if you haven’t heard about it, check here: 
http://www.cbs.com/primetime/armed_and_famous/ ) which features a group of celebs (such as La Toya Jacson and Erik Estrada) training to be real police officers.  Now that's good entertainment.
