I live in a pretty seedy part of town, so I figured I needed some protection from the local riffraff.  I tried a Wizard Hat but that had zero magical powers without the expensive wand and I ended up getting laughed at & mugged.  I figured an army helmet would show those thugs I meant business.
The other day as I was locking up my ten speed, someone tossed a molotov cocktail and it bounced off my protected noggin.  Thank goodness those idiots forget to light it.
