Da Crud

I've got the crud...and some weird part of me wants to determine ground zero.  Yeah, I want to know where I got it.  I've narrowed it down to two sources:  other humans and something I ate.  I'm going to go with the food theory as I find a particular restaurant much easier to avoid than humans in general.  Back to bed for me.  20 of the last 24 hours spent sleeping is not enough.  :-)
