This one runs nine minutes. It's one of my favorite burlesque sketches as adapted for the Abbott and Costello TV show. The man running the employment office is Sidney Fields, one of the great burlesque straight men. So was Bud Abbott. Lou Costello was the kind of comedian who sometimes needed two straight men.
The other thing that's interesting about this sketch is how many lines seem to be bobbled or ad-libbed. They were filming on a soundstage with no audience but still, they often didn't stop and refilm when someone stumbled on dialogue. Part of this was because these shows were shot fast and cheap, and they figured that since audiences were used to mistakes of that sort on live TV shows, you could get away with them on a filmed show. But there was also the fact that Costello hated doing multiple takes of scenes. He liked to get it in one and head for the track, and since he controlled this particular series, that's how it was done. It still turned out funny.
