It's a Mad, Mad, Mad, Mad Bar - S11.E14

Robin returns to Cheers, destitute. He has renounced his previous greedy ways, gave away the $6 million he had hidden in Rebecca's desk drawer and has decided to live a life of simple poverty. But admittedly, he still has feelings for Rebecca. Rebecca still has feelings for Robin, or at least for the $6 million she thinks he has. She thinks he's just testing her and that he still is rich. In the intervening time, Robin implied to the gang in an indirect way that he has hid another money belt filled with $6 million somewhere in the bar. Sam, Carla, Frasier, Norm and Cliff tear the bar apart, probe Robin and turn on each other trying to find the money belt. They then think that it was burned in the fire. But when they discover that Fire Captain Dobbins on duty the day of the fire is now retired with a sizable sum of money, they assume he stole the money.
