Bacon: I peed my pants.
(Bacon is a card carrying member of the CAP Society. That's Children Against Parents. Their methods are nefarious, devious and purely evil.)

Lovely Wife: What? You just went potty before we got in the car! Why did you pee your pants?
(Lovely Wife has recently joined POTLaN, better known as Parents On Their Last Nerve.)

Bacon: I don't know.
(CAP members are highly trained to withstand the fiercest interrogation.)

Bear: Because we don't have a bathroom in here!
(As the CAP Team Leader, Bear launches a flanking attack to support his troops.)

Lovely Wife: Gah!
(Bear's flanking attack is successful. Lovely Wife's adult thought processes cannot switch gears fast enough to counter his devious non sequitir.)

Bear and Bacon smile, content in their victory as Lovely Wife and I devolve into a laughing fit.
