I agree you with about the blood. I thought the concept was funny (I ate like a thousand blood caps) but the whole 3/4 angle thing with the hose is so old and played out.
Kind of like fart and burp jokes. You can have an amazing movie or show just bogged down by stupid juvenile tricks.
But again, I did enjoy the rest of the episode overall, personally.
PS Mack is seriously fucking fat as shit, lol. Awesome.
