Bubbles takes a liking into model trains.
- This episode's title is spoken in dialogue, and derives from the nickname Bubbles creates for Phil Collins, due to the fact that Phil was wearing a T-Shirt, which was stained with mustard, with a Tiger on it.
- It is interesting to note that Bubbles does not seem to have a large animosity towards Phil Collins; as noted when Bubbles conned the nickname "Mustard Tiger" for Phil. Despite the fact that this name was created in a heated moment, and Phil had called Bubbles "Four Eyes" (which angers Bubbles whenever someone does it), Bubbles seems to have done it out of a sort of affection. Evidence to this is given when, during a testimonial, Bubbles notes that he thought it was a "cute little nickname".
