Talk:Chalk and cheese

Different, not incompatible
IME, 'chalk and cheese' is more often used in the sense of 'different' than 'incompatible'. Googling would seem to confirm this.

Also, 'oil and water' is not a particularly 'American' phrase; an appropriate Google search produces plenty of UK-based hits. --Calair 01:07, 5 January 2006 (UTC)

Redirect to apples and oranges inappropriate
"Chalk and cheese" indicates complete fundamental dissimilarity, whereas "apples and oranges" indicates some broad similarities but also fundamental differences. See the discussion at Talk: apples and oranges for more on this. -moritheil Talk 01:15, 4 May 2009 (UTC)
