It is funnier if you take some breaks between watching it. It is very repetitive, and becomes Benny Hill-ish at times in that it is sometimes simply gratuitous sex and silliness. The season with Carla Cugina was the worst season of the show. Other times it is pretty good. I would give it a B or B- overall.
Go back and watch the episodes from like 2009 or 2010 when Eva Amurri is on. Susan Sarandon's daughter x2. Quite the specimen.
