Why does anyone require a 5 pound Hershey Bar?

Some guy in my office was given a 5 pound Hershey Bar as a gift.

My question is this: Why does anyone need a 5 pound bar of chocolate? Once opened, it tastes like crap. I'm pretty sure there aren't people who can eat a 5 pound bar of chocolate in one sitting.

Perhaps, it's not for eating. I'm sure it would make a fine paper weight. Also, it does look amusing carrying it around cause it is so huge.

Maybe, it can be used as a weapon? Whenever I travel on the subway, I always carry a 5 pound bar of chocolate for protection. Of course, it's possible to be mugged by a diabetic but probably unlikely.

I wonder why the Hershey people sell it. How do they promote it?

What would you do with a 5 pound Hershey bar?
