The clip comes from 'Tatort mit Til, Herbert und Udo,' a comedy radio sketch by German comedian René Steinberg that aired on WDR 2 on 13 November 2015 as part of an episode themed around France. The sketch parodies Tatort, Germany's long-running Sunday-night crime series, with a trio of bumbling investigators. 'Eierlikörchen' is simply the cutesy diminutive of Eierlikör, the traditional German eggnog liqueur, and its humor lies in how fondly old-fashioned it sounds. Lifted onto soundboards, the one-word clip survives as a tiny, warm burst of German comedy nostalgia.
