A woman was taking a shower. Her son walks in, and asks, "Mommy, can I take a shower with you?" His mother says, "Yes, just don't look up or down."
Well, like every other child, he doesn't listen. He looks down. He says, "Mommy, what's that?" She says, "Thats my garage."
He looks up. What a shocker. "Mommy, what are those?" She says, "Those are my headlights, sweetie."
Later that day, the father takes a shower after work. His daughter walks in.She asks, "Daddy, can I take a shower with you?" He says, "Sure, honey. Just don't look down."
Just like her brother she looks down.Didn't see that comin'. She says, "Daddy, what's THAT?" He says, "Honey, that's my car." After both children were satisfied with their parents' responses, they went to bed.
In the middle of the night, they both got scared, and went into their parents' bedroom. They say in unison, "What are you DOING?!?"
Their dad says, "Oh, mommy just turned her headlights on so Daddy can put his car in the garage."
