Don't you ever, EVER compare me to Family Guy, you hear me Kyle? Compare me to Family Guy again and so help me, I will kill you where you stand! Do you have any idea what it's like? Everywhere I go: "Hey Cartman you must like Family Guy, right?" "Hey, your sense of humor reminds me of Family Guy, Cartman!" I am nothing like Family Guy! When I make jokes they are inherent to a story! Deep situational and emotional jokes based on what is relevant and has a point, not just one random interchangeable joke after another! —Eric Cartman, Cartoon Wars Part I

Even Bart hates them:

Now American Dad, that's a good cartoon.

I think it was in the Rolling Stone article about South Park last year (but I’m not 100% sure), Matt and Trey said they got calls and gifts from the Simpson’s and King of the Hill people thanking them for calling out Family Guy.
