Little Johnny walks in on his mother in the bathtub.
He asks his mother what is the big fuzzy patch below her bellybutton.
She replies, โA bush.โ
The next day Little Johnny walks in on his father while heโs in the shower.
He asks, โWhat is that big long thing hanging between your legs?โ
His father replies, โIt is a snake.โ
A few days later, Little Johnny walks in on his mother, once again in the bathtub.
He asks, โWhat are those two baggy things hanging above your bellybutton?โ
She replies, โHeadlights.โ
A couple weeks go by and the little boy walks in on his parents having lovemaking.
He yells, โMom, turn on your headlights!
The snake is crawling into your bush!
