Average I guess at 6 - 6.5
but this is what I always tell everyone

Three midgets were sat around in a bar drinking when the first one, looking at his hands, says "You know, i think i have the smallest hands of any adult male in the whole world!".
The second one says, "That's strange 'cos i was thinking that i have the smallest feet of any adult male in the whole world!"
The last midget, looking down his beer glass at his groin says, "That's nothing, i think i have the smallest penis of any adult male anywhere in the world!".
After much discussion, the three friends decide to go to the Guinness Book Of World Records (GBoWR) the next day to see if what they thought was correct.
The next morning, bright and early, the first midget knocks on the door of the GBoWR - and 5 minutes later comes out with a certificate and a big smile on his face, "It's confirmed - i have the smallest hands of any adult male in the whole world! Ever!!".
With this, the second midget goes in - 5 minutes later comes out with a certificate and a big smile on his face, "Yes! It's confirmed! I have the smallest feet in the world - ever!!".
Lastly, the third midget enters the room - 2 minutes later he comes out looking really, really pissed off. "What's wrong with you?" enquire his two friends.
"Who the blue Hell is Bardog????"
