I read somewhere a while ago that it is. Similar to yawning when youre talking about it or see someone doing it you yawn. I think it only works if you see people doing it but i honestly think it is. Discuss! about anything that is.... not like illnesses or something.

btw, this video is quite amusing http://uk.youtube.com/watch?v=5P6UU6m3cqk

I don't find just watching someone laugh funny.
