completely agree , in every episode of the golden era i'm sure you kind find at least 1 reference, but who can forget http://www.youtube.com/watch?v=qWcZEfGFcT0
Homer: "And how is education supposed to make me feel smarter? Besides, every time I learn something new, it pushes some old stuff out of my brain. Remember when I took that home winemaking course, and I forgot how to drive?" Marge: "That's because you were drunk." Homer: "And how!"
I also always hated the 40s-50s references or the extremely specific joke references Family Guy made. The ones that I actually did get, they weren't comically funny, they were just funny because I got the reference. Simpsons would only rarely do stuff like that. The only thing I can remember was a short Thomas Pynchon joke.
