Leonard was technically not required to do anything for Shelbot since the wording of the section in the Roommate Agreement mentions becoming a robot, not using one to get around while the original body is still in use and intact.
On Sheldon's genealogical whiteboard, we learn he and Missy's other sibling is a brother named George, Jr.
The woman sitting with Steve Wozniak at The Cheesecake Factory is his actual wife, Alice.
ShelBot:: (in the car, while Leonard is driving) This is a photograph of the 1911 Solvay Conference on the theory of radiation and quanta. Using Photoshop, I've introduced a few anachronisms. See if you can spot all 24. I'll give you the first one. Madame Curie should not be wearing a digital watch. And go.
Leonard:: That's it, bye bye! (turns ShelBot off)
ShelBot:: (turns back on) BAZINGA! I have an override switch.
Leonard:: (after getting startled and nearly crashing) I almost DIED!
ShelBot:: And I'm safe and sound in bed, who's crazy now?
Leonard:: I'm still gonna go with you!
(Sheldon suggests taking up jogging)
Penny: Have you ever run before?
Sheldon: Certainly! I've run from bullies, dogs, angry chickens and one particularly persistant P.E. teacher determined to bend me over and give me a scoliosis test.
(Raj whispers in Howard's ear)
Howard: You're right, Penny jogs. Maybe you guys can run together.
Sheldon: That's an excellent idea! If we chat it will create the illusion of time going faster!
Penny: No, it won't.
