My sister is annoyed about family guy?

Tell your sister it's a cartoon, it's not real. HELLO! Brian and Stewie talk, if you can suspend your belief that it's not like only the baby and dog understand each other like on Arthur (I've had to babysit and watch that show, don't give flack), you should be able to stretch your imagination that Brian's given out an Academy Award, or Brian and Stewie have gone on these crazy trips and end up singing songs (like the Bing Crosby and Bob Hope "On the Road to..." movies). If your sister wants reality, tell her to stick to the news since she obviously can't deal with anything challenging it.
