The Haunted Helmet

One day many years ago, back when I was a young collector I happened to stop at this North Georgia Flea Market in the middle of nowhere. Soon I spied on the table a WW1 doughboy helmet offered for sale by this overall wearing older country picker. I might have paid 10 bucks tops.
Anyway, I brought it to my new apartment (I just got out of the barracks cuz I was getting married) and hung it on the wall. A few weeks later, sleeping off some beer I awoke to a smoky apparition in the doorway of my room. I was sooooo scared I could not move while it was floating there. But, I chalked it up to the beer and early morning sleepiness. Then, I got married and the wife moved in. Strange things started to happen like doors slamming in the middle of the house, and mysterious knocks.
Then one night I was sleeping on the couch (because of a fight) when I awoke to some strange sounds in the hallway. As I listened as quick as a flash this beast of some sort stampeded down the hallway and spun around right where my face was. It seemed like a boar but with red eyes. It seemed like a eternity but then it was gone. I had trouble beliveing on just what happened. The next day I finally told the wife about it and she then told me how last night something was touching her legs in the bed.

Sooo what happened to the helmet? My buddy was having trouble with this Ahole in the unit. So he gave this helmet to the Marine as a peace offering to get back some revenge!
