Pee shivers

Well when you urinate, your body is actually loosing some heat. Because that piss has been inside of your bladder for so long it's retained alot of body heat and when you finally piss it out your getting rid of all that heat, and especially on a cold day it may cause your body to shiver. This has happened to me a couple of odd times here and there.

Oh great, and the dogs a chihuahua too

You know they say when you get a random chill it is because someone walked on your future grave?

Well in this case it means someone pee'd on your future grave.

It’s actually recorded in medical text since the Greeks.
