the years of l'entre deux guerres

I saw a commercial for gum the other day that said the average person had something like 24 first kisses in a lifetime. It was really quite polarizing. Thought about it for awhile, and decided the type of people that have 24 first kisses are probably those sorority girls (& their male equivalents) who sat behind me in Geography of US and Canada smacking their horrible cow gums. People who have 24 first kisses are the people who impulse buy gum at the register.
