“If it snows on Chanukah can we build a snowman?”
Only if you make sure to take his cigarette out before Shabbos.
There was a story about that in an old “Best of Olemeinu” book, written by Rebbetzin Bulman zatsal. It was about a snowman whose creator almost forgot to take his cigarette out before Shabbos, and he was really upset about is so he davened to Hashem that the boy should remember before Shabbos.
Rebbetzin Bulman zatsal told me that it was based on a true story that happened her son. (Well, maybe some of the details were made up…).
