The joy of working with monkeys.

"Wake up it's evening treat time!"
What this really means is that I have medicine I need to trick you into taking, but since you don't understand it makes you feel better, I have to disguise it in different ways each time, as we all know variety is the spice of life. You do this barky howl, I call it a "hark" and then show me your behind in all of its glory, because you know that is what you are supposed to do. You happily grab your "treat" and eat it quickly, smacking your lips in the process. This makes me happy...but wait...your cheek pouch has a little buldge.
I decide to stay a little while to make sure you finish eating and give your friends similar treats (except they don't have the special one you got, it only looks like yours so you don't get suspicious of me), but I know to keep an eye on your actions. I see you follow my movements with the front of your body pointing towards me. I know what is to follow. You decide to prove that your bladder is working by an extremely accurate urine stream in my direction, actually following me as I move away(I will give you +1 point for that). Good thing I was paying attention and got out of the way(+1 point for me). I turn towards you and once again you show me your backside. Nice try to cover. I know what your up to. Then, I notice you finished your treat...........Ahhhhhhhhhhhhhh the joys of primate medicine (I wonder if human pediatrics have similar stories).
