I'm confused on one point. In an exercise in fatality, Milo says to Columbo that those cigars that he smokes are going to kill him. However I don't remember at that point in the show Columbo ever smoking a cigar in front of Milo at that point. Am I incorrect? Or is this something that the Riders overlooked?

That's a good catch. Did Milo say that as Columbo was lighting up a cigar?

I'd rather die young smoking cigars and eating chili (with or without beans) than live to 100 eating vitamin pills and carrot juice, lol.
