I do think my favorites were the group of teens, dressed normally but for the zombie make-up. I opened the door to give candy and they all went "braiiiins" at the same time. After a moment, one of them said "or candy". They got extra candy for that.
I sometimes get annoyed at teenagers continuing to go out ToT but this^? I'd get a kick out of it. They used some creativity about it!
I had a few teenaged boys who threw on some dark clothes and a mask and that was it. C'mon, dude! Put a little effort into it.
At least they were teenagers. We had a man show up covered in a black sheet and a full facial mask. He walked hunched over, but you could tell he was tall so I assumed it was a teenager. Until he reached out his hand for candy. I know it's difficult to tell age by looking only at hands, but the man's hands looked more like my grandfather's (80) than my father's (54). No way he was under 40, and he was quite likely a senior citizen. He was trick-or-treating with a similarly dressed girl/woman, but she was wearing gloves so I couldn't get a read on her age - but she was "adult" sized (so not like a small child). I suppose he could have been accompanying his teenage daughter trick-or-treating, but I thought it was a bit weird he expected candy. And I'm suspicious that the woman was his age.
If an older couple showed up decked out creatively for Halloween, I'd find it hysterical. But attempting to conceal your age with a sheet and a boring mask just seems to scream "I think I deserve free candy - give it to me!".
Not that it matters - no clue who they are and the both got candy.
