You know how you have friends over, and the afternoon light streams through the kitchen window right onto your oven, and it shows how the front (and back and sides) of the oven has The Cooties, and you worry that your friends will want to leave immediately and not eat the food you made for them because the thick film of visible grime over everything strongly suggests that they'll die if they do, and you want to burn your house down?
Yeah.
That.
