It's going to take more than one supergruff doc to scare off some of the new, impressionable faces serving under TV's House. Kal Penn, Olivia Wilde and Peter Jacobson, three of the newbies brought on to fill the "vacancy" left by the departures of House's previous assistants (played by Jennifer Morrison, Jesse Spencer and Omar Epps), are staying on as series regulars, sources tell the Reporter. The original plan was for just two of the new arrivals to be keepers, but have you seen the ratings?! It must be raining greenbacks at Princeton-Plainsboro!
