To the Moon and Back if You'll Be...

Conversation between a ~6yr old and his dad at the American Museum of Natural History in NYC

Dad: Hey look at this scale! If you step on it, it tells you what you weigh on the moon.

(Steps onto the scale)

Dad: I weight 5.6 pounds! Now you try it.

(~6 yr old steps on)

Dad: Oh, it looks like you don't weigh anything on the moon.

6yr old: Why??? (in a very distraught voice)
