Jim: You're taking the cosby kids to the pool.

dropping the cosby kids off in hell 

Dropping the cosby kids off in hell means taking a crap in the campfire.

Not a very popular activity.

When Fred squatted over the fire and began dropping the cosby kids off in hell, he burned his chode.

He got no sympathy.

submarining with the cosby kids 

Submarining with the cosby kids means diving down as deep as you can, dropping some logs, and then racing them back to the surface.

Not so cool in a public pool.

Serena was totally impressed with how deep Larry could dive, until the dooks started surfacing, and she saw that he'd been submarining with the cosby kids.

She didn't leave a note.
