How to answer the question, "where's yer brakes?"

one time in Clapham a very new roadie pointed out that I have no brake (I just brought the bike, couldn't even afford brake on it yet so was cycling it back to Wimbledon), that bloke look like he work in I.T. so when he went to ask the question while we're in motion, my respond is;

"oh it's voice command, watch this; STOP" (promptly slow down immediately).

the worrying thing is that I think he actually did believe that the bike is voice command.

Ha just spotted this, that's WICKED!
