Office gal: So last night I learned that human skin is essentially an evolutionary trait that allowed us to run!
Office guy: Okay…
Office gal: Cause it has more sweat glands and less fur, which meant we didn't overheat when chasing down prey…
Office guy: Great. (turns to leave)
Office gal: Hey, where are you going?
Office guy: To the bathroom.
Office gal: Okay, but come back because I have more things to tell you about sweat!
