This is a very odd installment of "General Electric Theater". Instead of the usual dramas, this one is a comedy starring Lou Costello. And, like some comedies of the day, this one features an unnecessary laugh track. This is because you often hear chuckles and guffaws when nothing funny is happening at all...and not much funny happens with this bland script...one which SHOULD have either been funnier or just not played for laughs.
Costello plays a plumber who receives a very unusual late night phone call. Some lady wants him to show up to a hotel dressed in nice clothes--not his usual overalls he'd wear to fix some plumbing. Once there, however, he realizes that some diamond thieves need his help and they're gonna get or else! So, the plumber tries delaying and then escaping when the crooks all fall asleep. When this doesn't work, he tries something else...none of which is funny in the least. This is pretty sad as it's one of Costello's last performances, as he'd die the following year...still a relatively young man in his early 50s.
