A few weeks ago, I recommended the tv series Psych as being pretty clean and hilarious.  Interestingly, we watched season 4, 3, and 2 before we watched season 1.  I would recommend doing the same.  The first season was a little bit naughty (mostly just the first episode) and I wanted to clarify that–We are still getting our nightly Psych fix as I picked up season 5 from the library just a couple of days ago.  and I still love it but it is interesting to watch season 1 unravel and develop into what it is now.
