I've been having some success with this:
At completely random point in the conversation, try to initiate a random game that seems impossible to play through words -- I've tried tic-tac-toe, duck duck goose, pong, and rock paper scissors.
Might sound weird, but this shit works -- here's a convo I had with an HB8:
(12:45:59 AM) crilleyfries: alright, rock paper scissors. it's on.
