I know this sounds weird, but my Mom likes Robot Chicken. We've watched quite a few episodes together and she really seems to laugh a lot. My mom is an "80s kid" so she loves the 80s references and seems to be a good sport about the more childhood ruining jokes. She seems to gross about sketches involving certain topics (masturbation being the main one) but enjoys the wackiness of it all. Her favorite character is The Nerd and I would have to agree with her on that one. Honestly, I'm surprised she likes this show because she doesn't like Family Guy, she tells me it's because they don't do the extremely long gags like the chicken fights and Conway Twitty on Robot Chicken.
