Pall Mall cigarettes had a significant market share in WWII. They were longer than regulars
by almost an inch, and the ads showed a fighter pilot holding up a Pall Mall beside a brand X
one. New Yorker magazine carried a cartoon showing Hermann Goering holding a long and a short
cigarette side by side, and saying to Hitler:"This means something to US Air Force, but
we can't figure out what."

My dictionary gives "pell-mell" = in wild, disorderly haste . You may rely on it, no American
lexicographer invented that pronunciation.

Here's a URL about it. Says it originated in France. So Paille Maille" got pronounced "pell-mell".
