I do not mean to pry, but you don't by any chance happen to have six fingers on your right hand?

Our reading
An editorial interpretation.
The speaker asks a very polite, oddly specific question: whether you happen to have six fingers on your right hand. The apologetic 'I do not mean to pry' makes it funnier, since the question is so pointed and clearly matters far more than the manners suggest.
