No Boston joke on season finale......

I kind of felt that he was hinting at a Boston joke or at least making a reference to it at two different intervals in the show. The first was during his monologue when he said something to the effect of stretching first, which had nothing to do with the bit at that the time. The second, was when he listed the 3 things he can't ever talk about and number 2 was something that was affecting the country currently and he wouldn't talk about because it would make people feel bad and that's not what comedians do.
