Storyline

Leonard, Sheldon and Amy run into Leonard and Sheldon's childhood hero Arthur Jeffries, aka Professor Proton, the scientist host of their favorite childhood television program. Because of this re-acquaintance, Arthur, who always wanted to be a true scientist as opposed to a kid's show host, asks Leonard to read and review a paper he is writing, but he doesn't ask Sheldon, which Sheldon can't understand. With some innuendo from Amy, Sheldon finally realizes that it's because he annoys Arthur. Sheldon tries unsuccessfully to make amends with Arthur so that he can collaborate on the paper. Without the friendship of his childhood hero, Sheldon decides to get a replacement model. Arthur makes Leonard truly examine his friendship with Sheldon, and in turn Leonard ends up getting Arthur to see Sheldon in a slightly different light. Meanwhile, Raj has been invited to girls' night with Penny, Amy and Bernadette. Raj's night with the girls ends up being taken over by an unexpected fifth. Written by Huggo

CHUCK LORRE PRODUCTIONS, #429

Dear Guys Working on the 405 Freeway, How's it going? I only ask because you started work over five years ago to add more lanes and, well... there aren't any. I've also noticed that on most days you're not actually doing anything. Is it possible you've grown bored with the project? I certainly would understand that. I've got more than a few half- finished scripts sitting in my desk. Of course, when I blow off my job millions of commuters aren't, how shall we say... fornicated. (Hey, maybe we should call it the 4-nication-05 freeway!) Regardless, I just want you to know that I'm rooting for you to complete your Herculean task and cut the ribbon on what will undoubtedly be a meaningless effort to ease traffic. I'd also like to offer up a few suggestions. From my untrained eye, you appear to be understaffed. Perhaps you might consider hiring a few thousand more guys and work in 'round the clock shifts, instead of, you know, just when you feel like it. Also, to avoid angry commuters flipping you off, how about giving them a heads up when you close an off ramp for no apparent reason? (Maybe a few miles in advance instead of a hundred yards.) And finally, I need to ask a small favor. Several times a week I crawl along the ol' 4-nication-05 with a bladder that is near to bursting. How about we work out a system where I, and other urinary-challenged drivers, get to pull over and share your port-a-potties? Maybe we can repay your hospitality by bringing you fresh magazines to read while you're in there working.

Sincerely, Chuck Lorre See more »

Bob Newhart made a welcome return appearance in "The Photon Displacement" ep of "The Big Bang Theory"
19 November 2013 | by tavmSee all my reviews

In this ep of "The Big Bang Theory": Leonard, Sheldon, and Amy are at the drug store where they bump into Professor Photon a.k.a. Arthur Jeffries (Bob Newhart in a welcome return guest appearance). Of course, it's Sheldon who bothers him thinking they're now good friends. Dr. Jeffries later e-mails Leonard about helping him on a project which bothers Sheldon. Meanwhile, Amy, Bernadette, and Penny are hanging with Raj making jewelry when Howard stops by and offers help. I'll stop there and just say this was another funny ep of "The Big Bang Theory" with another good performance by Newhart and an amusing cameo by Bill Nye, the Science Guy. So on that note, "The Photon Displacement" is another good enough ep of "The Big Bang Theory".
