What do Jews do on Christmas day? Great question.
I attempted an answer in this quick video vignette. It appears that we order Chinese food and watch football games we don't necessarily care that much about.
Though this ethnography is not the definitive documentary on the subject, there is a high-degree of accuracy in random sampling. In the past we've also been seen volunteering at soup kitchens going to see bad Adam Sandler movies, and taking advantage of low airfares.
