Damian Hurley, who plays Hansel von Liechtenstein, is the real-life son of Elizabeth Hurley, who plays Queen Helena.
When the queen talks with Prins Hans at the end of the episode, he says: happy birthday mum. Elizabeth Hurley and Damien Hurley are mother and son in real life.
The scene freezing and Liam talking to the camera to tell what happened is very reminiscent of Saved By The Bell when Zack Morris would do the same thing.
