An Australian goes to buy a condom at a nearby chemist.

The lady behind the counter gives a choice of three types. German, French, and Australian.

Whats the difference, he asks?

Well, the Germans are quite active. They have 7 in the pack. One for Monday, one for Tuesday, and so on. The French are very passionate people. They have 8. One for Monday, and so on, and 2 on Sundays. The Australians, well, they have 12.

At this, the Australian swells up with pride, Really 12?

Yes, 12. One for January, one for February…
