Why would people laugh non stop at a Mexican sculpture statue?

I find this very interesting. I was visiting an old friend we decided to go to this traditional Mexican museum I love learning from other cultures. Now in this museums they had all different kind of Picasso Art and other beautiful Mexican Art sculptures nice things people created with their own hands just beautiful talent. We came across this interesting statue it only had a head and a box no legs or arms just a head and a box with a mohawk. Once my friend look at the statue she started laughing hysterical. I mean she was on the ground she couldn't stop laughing at the statue to the point people call the ambulance. Yet she couldn't stop laughing. What was going on? I didn't nothing funny about this statue. It's not like the statue was mechanical you press a bottom to get the statue to make a funny dance. It just place there? Why? What's so funny about it? Forgot to mention my friend did the same thing when she saw my older sister African and Egyptian Mask collection. How is culture art funny? I will download a picture and tell me if it's funny or just normal? Why would my friend laugh at traditional sculpture, statues, Mask?
