>I think you should ask Rhubarb in which cheek his/her tongue was when he/she was carrying the diets in question.

I love the puns and word play, the tongue in cheek, the "nod, nod, wink, wink", but I am total helpless. I am literal!
I love best the literal comments–TEd Remington's comments about still pease in the pease porridge thread,

I get the puns, well most of them, I speak American English, but also know a good deal of english English. Its easy to learn it, there are plenty of opportunites to read, (the Economist), and listen to, (lots of BBC broadcasts are available in NY)that varient.
