Barney and Thelma Lou have an argument. They reconcile quickly, but it leads to other arguments between Andy and Barney, Thelma Lou and Helen, Andy and Helen, and another between Barney and Thelma Lou.
When Barney and Thelma Lou have a big fight and Barney declares their relationship over, Andy tries to soothe things and says maybe it's all for the best. Barney and Thelma Lou reconcile and when he tells her what Andy said, she becomes incensed and refuses to speak to him. When she relays what Andy said to Helen, they end up having a fight and Helen breaks up with Andy. It all goes round and round until Barney and Thelma Lou decide they have to do something to get Andy and Helen back together again.—garykmcd
