When Howard says he is 10 years older than Vince they stop and stare at the camera. This is a play on the fact that they change ages through out the show. In the previous episode (Strange Tale of the Crack Fox) they talk about how they are the same age and have spent their entire lives together.
Howard says that he's ten years older than Vince. In reality, Julian Barrett is five years older than Noel Fielding.
Howard is said to be 32 in this episode, making Vince 22. In reality at time of filming Julian Barratt was 39 and Noel Fielding was 34.
All four members of the Fielding family make appearances in this episode. Noel Fielding as the main character Vince, Michael Fielding as the character Naboo, and their parents Dianne Fielding and Ray Fielding are the shaman with the yellow hair and Chris De Burgh respectively.
