Your reaction is not at all surprising, as The King of Queens & 2 Broke Girls are just exercises in abuse and insults with the label "sitcom" slapped on it. Some comedy writers think over the top characters and situations are what makes good humor, but they would be very wrong. In the case of TKOQ, what's funny about a whining dullard of a husband obsessed with eating and arguing against anything other than watching sports? A wife who was constantly physically and emotionally abusive to the husband, materialistic, hateful toward just about everyone other than her conniving, thieving, screaming father? That is all TKOQ was--anything but funny.
2 Broke Girls--I guess the producers thought a group of characters being as base as possible is a reflection of the world, thus they're relatable. Honestly, who on earth could listen to more than 5 seconds of Kat Dennings' character telling 5th grade "gross-out" slurs & jokes without hitting the mute selection?
