I like the expression on eureka
Actually no idea whats going on
But still like the expression

lmfao this is the worst imaginable joke

What is the pun here?

I guess I'll explain it: The exclamation "Eureka!" was attributed to Archimedes. Hence...

ah... it was way too simple then, I was trying to connect it to the Pani Poni references.

Also I never picture Archimedes as a dancing naked guy, though I suppose that also happens in the Eureka story.

Archimede, after his discovery, went out naked running in the city of Siracusa shouting "Eureka! Eureka!", and they are 7 in this pictures cause of Eureka 7, but well, thought you figured out that much.

At least that's how the story goes, anyway.

So who are those two in the back? Socrates and Aristotle? Plato maybe?

not just a few old guy who needed (ya right) and excuse to run about naked for no apparent reason

OMG
im dead

Oh god why are Sauruman (or maybe gandalf the white, it's hard to tell) and Grandpa-Sensei in the background.

With the explanation of the old guys, Eureka's expression makes perfect sense then...
