Cul de Sac: My home is crawling with philistines.

When you see the "Trope" label down at the bottom of a post here, it usually means I'm annoyed with a comic for being hackish. But that's not the case with this Cul de Sac. This is a really simple joke, and one everybody's seen a million times before, and yet it works. In general, the difference between a well executed trope and a poorly executed trope is the quality of the characters and dialog that surround it.
