I doubt I'd ever respond this honestly to trick-or-treaters, but I used to envision this scenario years ago:
Trick-or-treater: Want to hear a joke?
Me: No, thank you. Not now, and probably not ever. Chances are, you didn't write it yourself, so you can't claim credit for it. Most likely, it's either an old, unfunny supposed witticism with a punchline anyone can see coming, or it's inappropriately blue for your age. Here are three mini candy bars for you, though. Happy Halloween and goodbye.
It's probably best that I haven't answered the door for trick-or-treaters in years.
