PUNISHMENT OF PAIN AND SCIENCE! (2014x61)
:
In which Hank is Punished by sharing the science of pain while he experiences various forms of pain.
If you're wondering, the most painful thing I did, oddly enough, was the brain freeze. I think I pushed it past the place where you would normally get a brain freeze by a couple of slurpee sips and that caused a really significant ouch.
Second most painful was the funny bone....then the muscle stress.
