Since it looks like the days are numbered for sitcoms in Get TV's early morning time slots, I thought that it would be a good time to rank the rare and sometimes unusual sitcoms they played before dawn (sometimes):

1. Ensign O'Toole
2. Jimmy Stewart Show
3. Nanny and the Professor
4. Peter Loves Mary
5. Mrs. G. Goes to College
6. Girl With Something Extra
7. Ghost and Mrs. Muir

I think they also had Peter Lawford in The Thin Man for a bit, but I'm not sure if that's technically a comedy. The dog was cute.
