I like the one where they actually leave. They have several flat tires and because they left so late most of the stores are closed. They try jeryrigging the tires because of course they don't have enough spares. Then BANG. The brain trust that is Brown family noticed a motel on the next exit. When they show the tires they are bald, bald, bald. Much pissing and moaning is involved. Prime Brown logic at it's finest.
