When Martin was interviewing Varnell Hill (played by Tommy Davidson), Varnell mentions that he has a "10-mile lake out back" and that "the catfish are delicious!" The line about the catfish was totally improvised by Davidson, which causes Martin to laugh almost uncontrollably. When the camera pans away from Martin, you can hear him laughing in the background.
This is the second time that an "In Living Color" cast member has made an appearance on the show. The first was David Alan Grier, then Tommy Davidson and finally Kelly Coffield in season 3.
