The final countdown is on: After years of demands, cult-comedy hit Arrested Development returns on May 26, when Netflix will stream all 15 episodes of the fourth season. After all this time (seven years!), we're not exactly sure what to expect, but Tobias better be wearing jorts, and Buster better be saying "hey brother." Those, of course, are just two of the program's 76 signature gags, jokes which came to define Arrested Development as the show moved from fledging primetime player to DVD darling. A number of those yarns were incorporated subtly, requiring repeat viewing to catch (even the most ardent fans admit to noticing things they've never seen before). These 20 gags, however, are the cream of the crop – and the ones that we hope (and expect) will pop up again and again in the new season and forthcoming feature-length film.
