I remember those days

Yes Grant that's the one that I meant. I can't believe that I did a rookie mistake like that. Oh well I guess it shows that I'm getting old

All joking aside, maybe it was just the word "ashes" in that title that threw you.
After all, Milo has those two really good lines about Columbo's "cigar ashes."

I also am not a cigar fan, so I sympathize with the characters who are irritated by Columbo’s smoking, especially when he is careless or inconsiderate with the ashes. Yuck.
