Communication with John Travolta via cerebal cortex possible!

My lunch was pretty boring today. If you have been following the recent trend, you will have guessed that I had a wheat bread + ham + turkey + cheese sandwich. More interesting than my lunch however, were these two people, who four feet from my office window sat in this position for the best part of an hour. I think they may have been communicating with John Travolta. What do you think (or know) ..?
