Second Halloween Tree T-Shirt

There’s a joke about computer programmers (or, I suppose, mathematicians) about the difficulty of distinguishing Halloween and Christmas, because the dates refer to the same underlying value … 31 Oct(al) is the same as 25 Dec(imal). I’ve long tried to figure out how to make this into a good graphical joke for holiday cards, but never quite got it. A couple months ago, the idea collided with the oft memed still from the Fellowship of the Rings, in which a hobbit asks “but what about second breakfast?”. Clearly, Christmas is just Second Halloween! Obviously, without text, this works for First Halloween, too. :)
