Most parents probably realize that the cartoons they show in prime time are not really meant for kids. Example of the day: American Dad. Stan comes home from work, and Francine says, “If I’d known you were going to be home so early I wouldn’t have taken care of myself in the bath earlier.”
As Quagmire would say, “Gigity Gigity Gigity!”
Update: And on Family Guy, “Spit on me. Now tell me I’m scum.”
