Snakes and Bushes
A young boy walks in on his mother in the bathtub. He then askes his mother what the big bushy thing is right under her bellybutton. She replies, ''A bush.''
The next day the young boy walks in on his father while he's in the shower. He askes, ''What is that big long thing hanging between your legs?'' His father replies, ''It is a snake.''
A few days later, the young boy walks in on his mother, once again in the bathtub. He askes, ''What are those two baggy things hanging from under your neck?'' She replies, ''Headlights.''
A couple weeks go by and the little boy walks in on his parents in bed. He goes over to them and yells, "MOM, TURN ON YOUR HEADLIGHTS! THE SNAKE IS CRAWLING INTO YOUR BUSH!"
