What Age is Too Old to Trick or Treat [POLL]

It's happened to all of us from one time or another.  We're enjoying a nice Halloween, answering the door and giving out candy to kids dressed up for Halloween.  Then, it happens.  The doorbell rings, and when you open it, there is a flock of teenagers bigger than you at the door, wearing costumes that they through together at the last minute, demanding your best candy.

True story, one Halloween when I was working in another town, I opened the door and there were three teens saying "trick or treat" in no costumes, an two of them were SMOKING! I kid you not. I told them to get the heck off my porch and to go home.  So, my question is: How Old is Too Old to Trick or Treat?  Take the poll below, or click through to take the poll and get some VIP Points.
