I know it's past Christmas but there's still time for a Christmas joke!

Santa: *climbs on the Hermes cabin roof searching for a chimney*
Movie Luke: What are you doing?
Movie Luke: Don't walk on my roof!

I know what your thinking, no Santa isn't a demigod or a god. But he has to deliever the presents right. Dionysus gives him special entry since he dosen't want to deliever the gifts himself.
