For sure Saturday Night Live. Although, as most people can see, it has gone downhill over the past years, and it is nothing that it was back in the days of Farley, Sandler, and Myers,.. it still somewhat contains some educated, yet funny humor. Mad TV on the other hand, has the same bathroom humor skits every episode. Now don't get me wrong, I love the occasional fart-joke, but to see it 15 times in every episode, it just doesn't please me. I don't think out of the 100's of Mad TV episodes I have viewed, I have laughed out loud more that 5 times. To me, that's dissapointing...
SNL all the way.
