Some child waking Christmas morning to find Santa dead from head trauma might just be the most horrible moment for the rest of their lives. Remember that scene in Gremlins where Phoebe Cates describes finding Santa dead in her chimney? It scarred an entire generation just hearing that story. For shame, Super Mario.
RICK: Covering the chimney with this warp pipe.
RICK: This year I want both Santa and Super Mario to visit!
JIMMY: But if Mario comes down the chimney and lands on Santa's head, won't it kill him?
RICK: Already thought of that. This chimney's occupied!
