Rain? I don't have that as my London stereotype. In the US, the stereotype I know is "foggy London." Which I believe was literally accurate until the passage of the Clean Air Act of 1956, following the killer fog of 1952.

Chicago's inaccurate nickname is "The Windy City." Wikipedia collected all the numbers for me:

While Chicago is widely known as the "Windy City", it is not the windiest city in the United States. Some of the windier cities recorded by the NOAA/NCDC are Dodge City, KS at 13.9 mph (22.3 km/h),Amarillo, Texas at 13.5 mph (21.7 km/h), and Lubbock, Texas at 12.4 mph (20 km/h). Chicago is not significantly windier than any other U.S. city. For example, the average annual wind speed of Chicago is 10.3 mph (16.6 km/h); Boston: 12.4 mph (20.0 km/h); Central Park, New York City: 9.3 mph (15.0 km/h); and Los Angeles: 7.5 mph (12.1 km/h).

I live near Boston and have visited Chicago many times, and I agree, Chicago, doesn't seem particularly windy. Chicago was a pioneer in building skyscrapers, which concentrate wind at their bases, and that, together with its lakeside location, might have created an impression that it was "windy."

In the United States, there is an inaccurate stereotype--promoted, of course, by boosters and tourist agencies--that it is always sunny in Florida. It rains quite a lot, and has bad thunderstorms that knock out power and Internet service. I remember being in Walt Disney World when the streets were six inches deep in water following a downpour.

In my experience, Germans have a very similar sense of humour to us, Britons. We think we definitely laugh at the same things.

Also, as Olga rightly says, we should really believe that the opposite might actually be true! Keeping an open mind is the key to everything, I guess.

I was once in Brighton, I stayed there for about two weeks in August. It rained one day out of 16-18 ( I don't remember). Since then I don't believe stereotypes :D Ok, I've never thought it is true, in fact. This is what the word 'stereotype' is for - to stop people from believing something, not to promote them. It often works the other way round though.

"You (Russian people) say "На здоровье!" ('na zdorovye!') when you toast and clink glasses, right?"  - NOoo! Nobody says that these days! Neither do my grandparents or even great grandparents! :)

At first, I was tempted to share more stereotypes about Russia. But I won't. Moreover, I'm quite sure some people will share some of them here later :)

No, it doesn't snow every day of the year in Canada.

No, we don't live under 5 meters of snow all year long.

And not everyone pronounces "about" as "aboot"... well... OK, forget that... maybe we do :)
