- Thomas: Yes Homer, but sometimes everything happens at once, I have to see Mayor Quimby to get my orders right away. The journey from Sodor keeps getting bumper and bumper.
- Homer: Does it? (Thomas blows his whistle) Sideshow Bob is back Thomas. You better be careful.
- Thomas: Mayor Quimby warned me about Sideshow Bob. Don't worry Homer. I'll just pop in and out with my sparkle wherever he goes and keep him in order. I hope.
