Good suggestion. That was my thought too.
Hey you know what I just noticed? You know how people are comparing the Muppet and Simpson's figs? Well, I was watching the Muppet Show today and then I sat down to watch the Simpson's. Those shows themselves have something in common that I never realized. The same opening "gag".
After the production number, Gonzo blows his trumpet. After the first few episodes, although the production number remained the same something different happened every time he blew it. In the Simpsons, same thing. Same opening credits (except for the chalkboard) and then it finishes with a different gag as the family rushes to the sofa.
Never realized that until tonight. Thought I'd point that out,
W-E-I-R-D....
