Gene, who had been previously horrified by his own inaction when Tina was about to get hit by a pair of falling shoes, goes with his father to prove to himself he has the ability to take action in bad situations.
When Bob refuses to leave, Sheldon attacks him with a drone outfitted with a long metal rod for poking.
Bob and Gene “regroup” in a dumpster and return to find Sheldon waiting for them with several fish-shaped drones, which shoot B.B.
He meets an employee named Terry, who informs him Sheldon used to work at the Hobby Hole before he was fired for stealing food from out of the fridge in the break room that didn't belong to him and for attacking his co-workers with helicopters – including Terry, who still has a BB pellet lodged in his knee.
This episode succeeds because it identifies unusual ways to combine the five core characters, and those interactions are just unfamiliar enough to add that extra zip to the gags.
This made it the fifth most watched show on Fox that night, behind Brooklyn Nine-Nine, The Simpsons, Family Guy and The Last Man on Earth.
