Because they can't move fast enough to flick a booger
Those little guys don't hurt anybody. They just chill all day.
By trying to jump rope.
When it's snot.
Don't wipe boogers on Mommy's pillow! Wipe it on Daddy's
To flick through it as fast as possible.
No IT guys change light bulbs, they just keep flicking the switch on and off again until something happens.
