Kerfeld gained fame for giving a drunken interview live to Bill Worrell and HSE in the Astros locker room after they clinched the NL West on September 25, 1986. The display was typical of his good nature and gregarious manner. Kerfeld was seen drinking a Busch beer during the interview, and then later pouring it on Nolan Ryan while Ryan was giving an interview with Milo Hamilton. Ryan retaliated by spraying champagne in Kerfeld's face. The clip can be found on the website YouTube.
