Here's something to think about (though not for long.) Once I was in the Everglades of Florida, talking to a Scotsman named Campbell. He jeered at Mrazek Pond, saying "M-r! How is a person supposed to pronounce that?"

Later, I realized that I should have replied, " And m-p-b! (as in the middle of Campbell) how is a person supposed to pronounce THAT?"

Now really, when English speakers say "br" all the time, is "mr" so hard?

Mooman: interesting observation about Knightsbridge. That is a lot of consonants in a row.
