"<a href=""https://www.youtube.com/watch?v=G025oxyWv0E&amp;t=2m00s"">2:00</a> Hm i always thought these "same-room-illusions" where an ironic statement like "hey we're obviously miles apart but we show our mental connection by doing this"... They also do it when one person does multiple takes to sing like a choir or something and obviously you can't be in the same room with a copy of yourself unless you're a twin", so just some fun?
