son: stop that!
mom: why?
son: she's pretending to fart on me.
mom: so?
son: she's pretending it's funny.
mom: well it is funny (daughter snickering some more.), and besides, you do it for real and think it's funny.
son: well, only 4 times.
mom: see?
daughter: yeah, but you fart and don't even know it and you're stinky.
son: yeah, but she's done it maybe like 2 million times.
mom: i don't think she's old enough to have said "fart" 2 million times.
daughter: uh huh.
mom: i think it would probably take you about 20 years to pull that off.
daughter: not if you went non-stop.
mom: *sigh*
