Sheldon has just located his childhood hero, Arthur Jeffries Ph.D., online. He was better known as Professor Proton, host of a children's science show. Both Sheldon and Leonard were faithful viewers when they were children before the show was canceled. Professor Proton is still available for special appearances, so Sheldon decides to hire him for a small gathering at the apartment. When Jeffries arrives and finds only Sheldon, Leonard and Penny, he is confused as he expected a party full of children. But performing his Professor Proton show to the three allows him to open up about the dichotomy between the wants of Arthur Jeffries Ph.D., and the realities of Professor Proton. Meanwhile, Raj asks Howard and Bernadette to babysit his pampered dog Cinnamon for him. This babysitting experience demonstrates to Howard and Bernadette whether they are ready to graduate to having a real live baby.

CHUCK LORRE PRODUCTIONS, #414
On what is perhaps the most bewildering experience of my life, I have, for the most part, chosen to remain silent. There have been times when it felt like I was actually swallowing my thoughts. But this comes at a price. Suppressed cogitation tends to gestate. It grows into something else. Self-immolating bitterness is one of the outcomes I've tried to avoid. That has tumor written all over it. Alternatively, these thoughts could morph into something beautiful; Superman's diamond wrought from a lump of coal comes to mind. But one thing's for sure, whatever the hell is growing inside me has to eventually be pushed out. Once it arrives, I'll leave it to others to decide if its metaphorical journey into daylight was through my metaphorical vaginal canal or my metaphorical ass. See more
