One of the funniest things that seems to be actually kinda accurate is the thing where Sigmund Freud said "All young boys when learning their mother doesn't have a penis, is convinced their father took it from her and is scared it will happen to them." It sounds like complete bullshit right? Like he's just making shit up? But here's the thing:

Consider a kid, with a penis, learning their mother doesn't have one. This is their mother! The only other person they really know on a deep level (except their dad, but in that time period few fathers were actually involved with their kids on that level.) and they don't have this ONE part of them that they do? It's completely absurd! A male kid's mind will go to all sorts of weird places before eventually accepting that some people just. Don't have penises. In a time period where lots of kids are terrified of their dads because corporal punishment is still a thing, I don't doubt Freud met a lot of kids who genuinely did think that at that time period.

You know how I know that? Because when I found out, my mum took a video of me who was trying to argue that my mum was actually hiding her penis as a prank. I love my dad, still do, and my mum is a very independent person, so I never thought HE was involved in this shenaniganry, but I was still 80% convinced their was a pocket or somewhere that my mum was hiding her secret penis, for some reason. I don't know when I finally accepted she was telling the truth, but GOD is it funny.
