I can manage dozens and dozens, which isn't meant to be showing off, as it's debatable whether the sentences make enough sense to understand, what with all the sub-clauses (you know, the little asides that, if you were writing them, you would write in brackets and between commas) which can sometimes be somewhat tangential to the subject (and are sometimes even (for example, like this bit (and this bit too) just here) nested very deeply inside each other), and my weird way of using wave upon wave of figures of speech and words which not all the peeps can grok ('appen even fallolloping 'ither 'n' thither twixt t'local tyke and a much posher dialect), and, of course, not strictly meaning multiples of twelve when I said "dozens", and... [
gasps for breath before passing out], and..., and..., um..., err..., sorry, what was I talking about again?
Other times, just getting a vaguely positive/negative sounding grunt out of me can be hard work.

You make a good point in that speech is more qualitative than quantitative.
