(The Janitor walks around the corner with his shoes untied)
J.D.: Your shoe lace is untied.
Janitor: Eeee, thanks man. Do you know how dangerous this is? My uncle's whole family was killed by an untied lace. They were running down the stairs and they tripped and a mad man hacked them all to pieces, I owe you one.
J.D.: Can't wait.
