Toothcomb??

Is it possible to comb your teeth? Personally, I brush my teeth, but comb my hair (sometimes). But I recently read an advertising e-mail (not spam, I did request it) urging me to go over the document with a "toothcomb"! Duh!The English expression that means to examine something very closely, to look at the little details is 'to go over (something) with a fine-tooth comb', that is, a comb with fine teeth, not a comb for your teeth!I'm not immune to these types of mistakes, so I won't do any more Mickey-taking. Just to say that while looking for examples of 'tooth-comb', I stumbled on this marvelous site by an American professor. Have a look sometime, it's got some great stuff: errors in English.
