The writer really did a fabulous job of taking his own "surprise birthday party" and translating into this awesome episode. The original surprise party actually happened during college, and the entire guest list, party location, etc. was planned by the guest of honor(the writer of this episode). Of course, in this episode Whitley is out-smarted by Dwayne. In the original party, the guest of honor outsmarted everyone.
This episode is the best of the series, because it has a feeling of truth to it. Who hasn't wanted to plan their own surprise party? And who hasn't wanted to out-smart the perosn who always has to be the center of attention?
