In this fair but average closing episode of the second season, Richie, Potsie and Ralph go with the school choir on a trip to Chicago.
On the night before a big performance, Ralph convinces them to sneak out of their hotel room and go and see a comedy show at a nearby burlesque house. But it turns out to be no laughing matter when they get the drinks bill.
This isn't a bad episode at all, but doesn't match up to some of the classics offered up in this season.
It is also noticably void of the Fonz, who only has a cameo at the begging of the episode. (He may also appear at the end, but the showing of the episode that I watched had the last scene edited out - damn you, Five US!).
