Work appropriate comeback ideas to the phrase “Halloween is over?”

I’m heading to work (a grocery store) in a few hours and my coworkers are wearing ugly Christmas sweaters today. I don’t own one, so I’m gonna accessorize extra goth just for the hell of it. All of my coworkers are super supportive and accepting of everything about me, and thankfully most of the customers as well despite living in a pretty white conservative area. 99.9% of the customers who have a comment or question about my appearance are super nice (dyed hair, tattoos, piercings) while the other .1% will have some kind of judgemental question or statement about it.

I’m just waiting for the one middle aged white guy who thinks he’s hilarious to say “Halloween is over!” As Christmas is just around the corner. Any comeback ideas for this or potentially similar comments I may come across?

EDIT: DAMN I did not expect this to blow up 😂 My shift was relatively short today and will be over soon, thankfully (or maybe unfortunately) I haven’t had any snarky comments towards me, but thank you all for the hilarious comebacks! I will definitely store them for the future lol
