That reminds me of the 3 parts of the cigar in French, which I learned when I lived in France and I was a cigar smoker:

• The first third is hay (“le foin”): it’s light and not very good
• The second third is divine
• The third third is manure (“le purin”): it’s tarry and gross

Two thirds of a cigar are not really enjoyable. Considering the cost of a good cigar, that’s not good value. Whoever said smoking was rational 🙂
