Janitor's Father: Hey, hey, hey! You missed a spot, right there.
Janitor: Well, lucky for me, Dad, I spend my life going in a circle around this place cleaning up after the sick. So tomorrow I'll probably be here at the same time.
Janitor's Father: You know that I hate sass, so drop right down and give me 20.
Janitor: Dad, that could be fecal matter.
Janitor's Father: Make it 30.
Janitor: Fine.
