Caskets are generally sealed in a concrete box of sorts. This concrete box is sealed with a several hundred pound concrete lid. Not to mention that moving that much earth is a back breaking job that would require several hours. You're thirteen, how did you move a corpse around? On your Radio Flyers?

This is just dumb, why did I even respond?

Edit:

I never thought I'd say this but to those of you who are taking this garbage seriously- you may want to consider cutting down on your marijuana intake.
