my parents used to sing me this song as a kid, but I'm struggling remembering the lyrics, can you help?!

Where will we be in 100 years from now?
They put you in, a big black box
and bury you 6 feet, under the rocks

woooooh ooh ooh ooh,
where will we be in 100 years from now?

Your eyes fall in, your teeth fall out
Your brains come trickling, out your snout.

woooooh oooh ooh oooh,
where will we be in 100 years from now?

The worms go in, the worms come out,
They go in thin, they come out stout.

Woooooohhh oooh ooh oohh,
Where will we be in 100 years from now?

There's another verse!!! What is it?!
