The long-running (and occasionally Oscar-winning) series of shorts narrated by a Smith called Pete tackles the the problem of mothers-in-law (notice where the 's' goes, youth of the IMDb!) and their place in slapstick comedy. Dave O'Brien is the husband, his real-life wife Dorothy Short is his wife -- see how that works out -- and Annie O'Neal is his wife's mom, a grim-faced, meddling, argument-provoking old snoop. And those are her good points.
Although most of the gags are telegraphed well in advance, there are a couple of very good ones. For those of us who enjoy Smith's snark, it's a lot of fun.
