9. The next day the man said to the woman that he was going to have a shower but the little boy said i want to get in the shower tooooooooo, so they both got in the shower and the man says whatever you do don't look down. So of course the boy looks down and he says, "What is that daddy?" So that dad says thats my Snake so the boy says o.k. Once they get out of the shower the mom says to the dad thaht she was going to have a shower and the little boy says but I want to have a shower tooooooooo, so they both go to have a shower and the mom says whatever you do don't look up OR down so of course the boy looks up AND down and when he looks up he says whats that mommy and the mom says those are my headlights and then he looks down and he says what is that mom and she says that is my garden so the boy says ok so they both get out of the shower and that night the mom and dad get into their bed and the little boy says but i want to get into the bed to so they say o.k.
