That was one of Futurama's weaker episodes even if you understand the actor allusion. If you don't get the reference, a lot of screentime is spent on a couple of the characters behaving in slightly strange ways for no apparent reason.
It's one of my favorites (when I saw it two decades ago) but I guess I get the references. I just thought Fry pretending not to know what a video game was and the internet being full of ads and sex still relevant? Bender also stealing everything was a delight.
The internet being full of ads and sex is still relevant (ads possibly moreso) but yeah it's not as fresh as it was. If anything the Napster episode aged worse than the plain internet one, but I think it holds up as an episode better.
Married With Childrens last episode aired in 1997 so it was in recent memory, and I'm sure you could watch a rerun of MWC same day this episode aired (March 19, 2000).
...if you cared to, which at least some of the audience likely did not. I'm sure the demographics of a live action present day dysfunctional family sitcom and a sci-fi cartoon don't perfectly overlap.
