One link led to another, and that led to this entry at Boing Boing, about what Christmas would be like if it were a Jewish holiday:
This is the fruitcake of our affliction, which our ancestors baked 400 years ago.
All who are in need, come and celebrate Xmas with us.
All who are hungry, come and partake of this 400-year-old fruitcake, as it is written, "Let them eat cake!"
This year we watch football in the living room, next year may the Super Bowl come to our city!
For the whole thing, see Have you ever wondered what Xmas would be like if it were a Jewish Holiday?... (Backup link in case the first is down.) Who can resist the Letter of Approbation from the Kringler Rav?
