Barney has invented something that looks to Fred like a giant egg beater, but it's a flying machine. Fred feigns illness so that he and Barney can get out of "opera night" with the girls and use the Flyer to go bowling instead.

It's Fred's responsibility this time around to assemble an act for Amateur Night at his and Barney's club.

Fred is mad at Barney for calling him stupid. Then Barney decides to build a swimming pool, and Fred talks his neighbor into sharing the pool with the Flintstones.
