This episode is in reference to when Will told his brother what he thought of his soon-to-be wife. With only a handful of script ideas and a push from the network to create a two-parter, David & Max took from the pilot and create these two episodes.
First of two appearances in the series by John Slattery, playing Sam, Will's estranged brother. The character was referenced in the pilot episode and would also re-appear in the final season, although this time he would be played by Steven Weber.
