Hydrofloor

Nah I think burning to death is evil enough. Or do you want him suffer even more by putting ice cubes in his mouth then duck taping it shut?

Now that's EVIL.

More like fill that pool with all the creatures of the deep sea and close him in their with a single oxygen tank (and respirator) and one flashlight with almost dead batteries.

Or lets recreate the pit of doom underneath that floor and then we can "prank" JB

But what if he survives!? We have to do something he won't survive

If that doesn't work then we'll hang him
