When the moon is full it sure can get crazy...

I start howling and eating people, never during the day light though, I save that time for hunting deer!

Seriously, I haven't ever been able to tell a difference one way or the other with the moon phase. There are stats to support both schools of thought. Moon phase vs. shorter days and colder nights, but you know how those crazy stats work... However you want them too, that's how!
