I'd say if a commercial like that works for a common US audience, the dozens aren't that big a secret.

Absolutely, Jeri, if you are talking about the USA. I am in England remember and it makes no sense to me at all. Even though I now know what the dozens are. Maybe it is a cultural difference or maybe it is just me! I can literally cry laughing at some of the puns and word plays by authors ranging from P G Wodehouse to Terry Pratchett yest not raise a snigger at things that others find hilarious. There is one man who certainly bridges the divide between UK and US humour for me - Bill Bryson. Anyone else a fan?
