The animators at Pixar are all grown folks, adults, over the legal age for everything and absolutely normal in every adult way, including a healthy libido.
That can be easy to forget when you consider most of the movies they make really cater to kids, keeping that PG vibe that made them such good friends with Disney in the first place.
But adults sometimes draw and animate stuff for other adults to enjoy, and back in 2003 animators Bert Klein and Teddy Newton from Pixar created this risque short called Boys Night Out. (Video is NSFW-ish)
Even though the storyline in Boys Night Out is all sorts of wrong, since it involves a stepfather and his underage stepson bonding at a strip club, this retro styled short is still quite charming, and the punchline will knock your socks off!
