Looking for Christmas drawings starting from a penis

Next month at work we have a special day where we are to put on the ugliest Xmas sweater. I want to create my own based on a penis. As a kid there was a dumb way to draw a sheep starting from a penis, but I'm looking for something simple based on Xmas, like Santa Claus or a reindeer.

The goal is to sew lights on the sweater that will light in a way to first show the penis and then the full Xmas drawing. I tried looking online but didn't really find anything.
