No - I agree. 5'-7" isn't exactly 'small'.
But the guy I was referring to was 5'-7" with boots on which had 1 1/2" heels. So he was like 5'-5 1/2". That's pretty 'small' for being the baddest guy in the neighborhood - which he definitely was. (he was the 'original Fonz')
An aside, Cowboy boots were great for starting the 'old' Harley XLCH as you never slipped off the kick starter do to the heel ("engineer boots" were passe' and too heavy anyway). And the pointy toe came in handy during a fight (why am I still alive? LOL).
