Hmm, well a few weeks ago I was watching a video on you-tube whilst my wife watched something I wasn't interested in and could not stop laughing. Does that count?
Otherwise I'm not too sure, had some big smiles yesterday Skyping, and I often think of something that amuses me and I just smile for no apparent reason. I think I'm weird. But nice, nice weird.
Do you think you are a just a leeeetle bit crazy?
