Head Banger

Walked into a ruddy stop sign today
Damn thing's been there for eons
Concentration lately is all shot to hell
It's the looney bin for me e'er long

They'll lock me up this time for good
Probably it's best that they do
Before I do some irreparable damage
And I wind up royally screwed

Thought I had things under control
Wear underwear most every day
But at times I'm known to wander off
Police bring me back when I stray

Bumping into things ain't a good sign
Quite famous all over the town
Forgetting to zip up after having a pee
Or even forgetting to zip down

So sad an ending to a productive life
Babbling to myself as I drool
But the friends I talk to inside my head
Understand me and think I'm cool!
