Hump day

Each morning my students do this word sort activity where they have to spell words and look at the similarities between them (incredibly exciting). Today one of the words was "hump" like the thing that is on the back of a camel. A boy raised his hand and said "My dad likes to hump," following by my mouth hitting the floor. He went on to explain that when he's riding with his dad in the car he always tries to go over all the humps in the road to make the car ride more like a roller coaster. Alright, now I've got it. Now I've seen both of this kid's parents and the last thing I want to do is picture them getting it on.
