When Johnny and Kate were learning to use a toilet....
Kate: this is it right?
Johnny: yeah....
Kate: so what does this do?* Points at the flushing leaver *
Johnny: careful Kate we don't know what that does....
Kate: only one way to find out * pushes the leaver down*.
FLUSH!!!
Johnny & Kate: * both run away screaming in fear*
This was inspired from a episode of family guy
