@tonscia Watson cannot buzz in until it knows the answer and after the host has finished reading the question (it gets a signal to this effect). Having buzzed in, the host will say "Watson" or something and a human operator presses a button to inform Watson that it is allowed to speak (to prevent it talking over the host: Watson cannot hear). The operator has no control over what Watson will say.
So Watson cannot stretch the rules like Ken did, buzzing in then umming and arring for a second or two.
