"They've been going out for a while and he's been getting upset because other guys have been asking her out. And she saying she can't help it if she's attractive and popular. And besides, nobody ever said they were going steady, and if he does want to go steady, he's got to do a lot more than just movie-burger-backseat, movie-burger-backseat, because there are plenty of guys with bigger backseats waiting to take her some place nice!"
