I liked Lou, but I was a Curly fan at heart. A lot of people don't realize how good some of those comedians were, but in the Who's on First skit, for example, their timing is perfect. I saw a movie about their lives, with Harvey Korman and Buddy Hackett playing the leads. Those two were excellent comedians, but when they did the Who's on First skit, the timing was a little off. When Abott and Costello do it, there's just enough of a pause that Lou appears to be thinking about it, and the audience has enough time to pick up on the double meaning. Lou jumps in with his comment quickly enough that it doesn't drag, though.
Remember Lassie, The Wonderful World of Disney, Perry Mason, The Donna Reed Show, Leave it to Beaver. I always wanted thought Donna Reed had the perfect family.
