I just don't get it

[Becky]

Let's all go grab our scales, throw em in our backpacks, get on our bikes, ride to the hilliest highest hill in town, you know the one... the one with the cliff on the other side? And CHUCK them babies right over the side.

(I know.
It's littering. But you get the picture.)

Take 'em to the dump and chuck em over that edge Here in Delaware, the dump is one of the highest hills in town- really.
