 Barney has a big problem: his water pipes are leaking. Though Fred with his ideas mess things up, the house gets flooded and the plumber forces Barney and Betty to get out of the house for several days. Fred offers them to stay for a while. However the wives are a bit concerned whether or not Fred and Barney will soon get in a fight. And it seems to come this way, since Barney s "at ease" attitude starts to annoy Fred s lifestyle, especially about mooching a bigger piece of cake, sleeping on table chairs, Barney s sleepwalking, a phone off the hook and last but not least, a pizza pie eaten by Barney itself !
