This is a great thread.
I know people like that too. They freak out if it's been 5 minutes past normal pooping time.

They're anal about it.
I know it's the wrong season, but the Mr Hankey lyrics come to mind:
Mr. Hankey the Christmas Poo
Small and brown he comes from you
Sit on the toilet here he comes
Squeeze him 'tween your festive buns
A present from down below
Spreading joy with a "Howdy-Ho!"
He's seen the love inside of you
`Cause he's a piece of poo
Sometimes he's nutty
Sometimes he's corny
He can be brown or greenish brown
(Mmmmhmmm!)
But if you eat fiber on Christmas eve
He might come to your town!
