To me, the original Tom and Jerry cartoons are timeless (the original 1940's ones). About a decade ago, I took the family to Brazil on holiday. One day we had a tropical storm, so stayed in the hotel room, found a channel showing old back-to-back Tom and Jerry, we were all killing ourselves laughing. Same thing happened a few years earlier at home, Sunday afternoon, raining, skimming through channels, found a channel showing old Laurel and Hardy, the kids started moaning "oh, not black and white stuff", I said just watch for a few minutes and see if you like it. It was the one delivering the Piano, and they ended up howling with laughter.
Good stuff is just good stuff.
For the record, I loved Top Cat and the Flintstones as well!, both had subtle jokes and references that adults would get.
