Wally has reprogrammed the sharkbot to get him coffee when needed. His Ipad has been plugged into the wall for continuous use. Talk about being ready to go...
Wally has all the bases covered from an episode many years ago. PHB said he couldn't fire or demote Wally because his evaluations were too high (?), so he would move him the worse location possible, the men's room.
Next scene, Wally, with power and internet cords running under the stall's wall, is bragging to his Mom "Guess who has been moved to a cubicle with a door!"
