There's an old joke (or maybe expression) about being able to tell how long a couple has been married by how many bottles of Tabasco they've been through. I can't find any exact numbers though. The implication is that most folks use very little Tabasco and so if they are on their 3rd bottle or something they've been married a very long time. I think it's a little outdated but it probably holds true for quite a number of people.
I bought Tabasco today. I think it's bottle #7 for us. The newest bottle, like several before, is the club-store size. Not the grocery store size. I guess we've been married about 180 years according to the Tabasco calender.
