37. Alex, I Choose Things At the Beach for $500

And the answer is "piles of sand erected on beaches during the winter months to help curb high tide erosion".

Insert game show music here.

"What are sand berms?" our contestant shouts out with pride.

To which Alex replies, "You are correct."

And to think I was mistakenly referring to these piles of sand as sand hills.  I believe this is simply another form of the truth of the theory of relativity in action.

To geologists and coastal engineers, these berms are a resource to curb shore erosion.  To beach residents, these berms are a resource to help reduce the risk that their home will be pelted by huge winter storm waves.  To a dad and his young son, berms are a safe place to take your saucer and share some sliding fun.  To a group of boys, berms are a fun place to see who can jump the highest and farthest.  To Blogger Bjork, berms are sand hills which have provided fodder for a blog post.

So class, what have we learned?  The sand hills at beaches are technically known as berms.  A sand berm at the beach can be many things to many people.  And this probably wasn't what Einstein had in mind when he came up with the theory of relativity.
