30 Rock has always been a finely tuned joke trebuchet. Much in the same way people from Seattle say “Don’t like the weather? Wait 20 minutes,” longtime viewers of 30 Rock could also assure themselves “didn’t like that last one-liner? Wait 20 seconds.” But thankfully, human beings usually require a little more from their art…otherwise networks would just air a slowly scrolling list of “yo mama” jokes in 30 minute increments (don’t get any ideas, CBS).
