I got to think, now i work at a photo lab in a CVS and i did a little experiment:

Usually u get one of those customers who u really want to punch in the face, but during a full moon on my shift i noticed that their were more crazy and angry people than anyday of the month

Maybe its me but i think the Full Moon makes people act different

It does

I've also noticed an increase in abnormal behavior during the new moon as well...

Did he turn really hairy and grew long nails and fangs?

I think you could be right about the moon affecting peoples moods mate, cos if you think about it our bodys are made up of between 50 - 65% water and just look how much play the moon has on the oceans an tides. An to be honest i don't think its a new observation cos the very word lunatic is taken from the word lunar meaning moon!?

I've read that the reason a full moon affects us goes back 1000's of years.
Apparently man was always nervous when there was a full moon because they could be more easily seen on these nights as it was brighter. They were then more anxious of being attacked by animals. Some say that this is the reason that some people behave strangely during a full moon, they are more ready to fight or take flight. Even though the dangers are no longer as real as for 1000's of years somehow our genetics remember this.

I agree.
