Gerry Turns 40 (5x13)

Air date: Apr 12, 2016

Gerry is turning forty, and after finding a letter he wrote to himself ten years earlier, he becomes acutely aware of everything he has failed to accomplish. Meanwhile, Simon's ferret goes missing and Lisa wants to impress the chairman of the board of trustees by putting on an elaborate fun fair in his honour, which quickly devolves into a complete disaster.
