Walk on your knees? 
That's exactly what I did in the GenCon scramble '09 when i was playing ChromeMonger..... I even had one of the other dwarves copying me. heh
It was great When I had to get "face to Face" with a dude playing a Troll (He was damn near troll size IRL) I grabbed a chair plunked to down in front of him knelled down in it and then leaned into him.....
