I don't think Family Guy has any room to make fun of another show's style of humor. That is literally the worst "comedy" program ever.
The whole without laugh track thing brings up a valid point with Big Bang, but I still enjoy it. It isn't gut-bustingly hilarious, but it does have funny moments. Even I as a fan will admit though, it's not smart humor and it definitely doesn't have creative writing. One thing that always bothered me about the show was how Raj would whisper into Howard's ear and then Howard would repeat it back so the audience knew what he just said. No one ever repeats back what a person just said to them. Maybe I'm over-thinking shyt here.
