If you’re confused: Birds are dinosaurs, crocodiles aren’t; note the “closest living relatives”
Though, isn't being part of a group the closest you can get in terms of relatedness?

Yeah, it's like being related to your family. Most people would consider your relatives to be related to you.
Are octopus related to octopus? I mean technically they’re 100% related, but also they aren’t related as related implies not being. Depends on your interpretation.
Are you saying octopus are all incest babies? Scandalous.
Ah sorry, the genome of octopus’ mating is only 99.99 something % similar. Not 100%. Rounding reflex.
Most people would consider your relatives to be related to you.
Really makes you think.
Am I my closest relative?
"Brother, am I not your relative?"

I actually just learned this recently, but dinosaurs differ from reptiles in that dinosaurs have legs that are under their bodies whereas reptiles have legs that splay out to the side. So all mammals, and birds, with legs directly under their bodies are probably more closely related to dinosaurs then reptiles.
No. Tetrapods and reptiles diverge well before dinosaurs. All dinosaurs are diapsids as compared to mammals, which are synapsids. A dimetrodon (the one with the big sail) is not actually a dino and is more closely related to humans than it is to dinos.
To expand on this concept, all dinosaurs and humans are technically considered bony-fishes as they are nested within the bony-fishes clade, osteoicthyes, but thats probably spelled wrong (this recently was used as a way of protecting some types of animals in a law that is supposed to protect fish as a category), and all birds are technically dinos, so when we refer to non-avian dinos, it just means dinosaurs excluding the birds!
Forgive my ignorance on the subject, but huh?
Clearly I missed a briefing somewhere. I thought that crocodiles were from that era, or is that the joke that I'm somehow missing?
The joke is that birds aren't only related to dinos, but are dinos themselves.
Yes and the cruel part is... Pterosaurs are not Dinosaurs!
It might be easy to brush off my complaint as a case of paleo-pedantry, but word choice matters. "Dinosaur" is a word for a specific group of creatures united by shared characteristics and which had their own evolutionary history—it is not a catch-all term for anything reptilian and prehistoric.
We have known about this distinction for a long time, and I bet that your average 10-year old paleo fan would know not confuse the groups.
So, it's a joke about the fact that both are essentially dinosaurs?
.. nope, I got nothing ..
Here's my take:
Low IQ: crosc looks like dinos so they are the cloests living relative to dinos. Mid IQ: birds are direct descendents of dinos so they are the closest living relatives to dinos. High IQ: since birds are direct descendent they are just dinos, not a relative. Which makes crocs the next closest living relative to dinos/birds.
No, the joke is that crocodiles aren't dinosaurs despite looking like them and being around at the same time, just closely related, while birds technically are dinosaurs, just not the big lizards of 64 million years ago.
So really, this is not a joke about dinosaurs at all, it's a statistics joke .. which would put this meme in the wrong community 😇
No, it's a joke about dinosaur taxonomy. A statistics joke would still fit though, this is science memes, not dinosaur memes.
I was making a joke about statistics not being science, but it's clear that not everyone got the joke .. pretty much the same as the original meme.
(This is humour, laugh.)
Statistics is maths, and maths is science insofar that you can't do science without doing maths. And I'd further argue that statistics is perhaps one of the three most important branches of maths to science, the other two being linear algebra and calculus. Also, it's been established previously that maths jokes are definitely welcome here.
