vague and disgusting

so, inspired by jules, i've been doing a lot of online nature trivia reading in my downtime (read: in my alwaystime) lately, and i stumbled upon a piece of shit website full of whale facts. well, it pretends to be full of whale facts, but in actuality it offers about six tasty nuggets of whale-genius.

this was my personal fave:
Some arteries in some whales are so large that a child could crawl through them!

as vague as it is disgusting, this fact begs one question: what about cavemen strippers? are there any whales through whose arteries a caveman stripper could crawl?
