The shitty end? We used a long stout stick in the kybo at camp to knock the pile over when it gets too high. Then sprinkle some lye on it. And sing (to the tune of "Downtown"):

When you are sleepy and it's time to go peepee
There's a place to go ... Ky-bo!
When you are droopy and it's time to go poopie
There's a place to go ... Ky-bo!

Listen to the rhythm of the froggies in the toilet
Even though it's smelly I am sure you will enjoy it
The lights are not
On in there, but forget all your worries
Forget all your cares in the...

Ky-bo!
Isn't it fun to go?...
Ky-bo!
Tell everyone you know...
Ky-bo!
Relax and just let it flow...
Ky-bo!
