Episode complete credited cast:


It's "Anything Can Happen Thursday", the third Thursday in the month the guys have deemed the day to do something different to get out of their rut. Sheldon proposes that they go to the comic book store (as comic book store night is usually Wednesday). Penny tags along to buy a gift for her nephew. In addition to getting something for her nephew, she also gets something else: picked up, specifically by Stuart, the comic book store owner. Leonard has mixed emotions: he is buoyed by the fact that someone that is somewhat like him at first glance can get a girl like Penny, but is jealous that Penny picked Stuart instead of him. To get over this situation, Leonard, with Howard and Raj, decides to do what Howard suggested to get them out of their funk: go to a bar to pick up desperate women. Written by Huggo

Did You Know?


The comic book over which Sheldon and Howard are arguing is issue #8 of "All Star Batman and Robin" with a variant cover by Neal Adams, issued November 29, 2007. See more »


When Howard brings up the Drake Equation, Sheldon fails to mention it is based on pseudo-scientific hokum, as it has an infinite number of variables and is thus not possible to actually calculate. See more »


[first lines]
[Sheldon moans]
Leonard Hofstadter: Problem?
Sheldon Cooper: This is Thai food.
Howard Wolowitz: Here we go.
Sheldon Cooper: We don't have Thai food on Thursday, we have pizza on Thursday.
Leonard Hofstadter: Yes, but we all agreed that the third Thursday of every month would be anything-can-happen Thursday.
Sheldon Cooper: Well, apparently the news didn't reach my digestive system, which, when startled, has its own version of anything-can-happen Thursday.

Crazy Credits

CHUCK LORRE PRODUCTIONS, #248 I believe that Newton's first law of motion is the reason we will emerge from our current economic woes. That law states that an object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force. How does that relate to the financial #$%*storm we're now cowering under? Allow me to explain. There are slightly less than seven billion people on this planet. Assuming that roughly half that number are either too young, too old, too lazy, or too loaded to work, that still leaves almost three and a half billion people getting up in the morning to chase the almighty dollar, the transcendent rupee, the zen yen,the dear ol' euro, the what's goin' on yuan, the... well, you get the idea. Now, call me crazy (and many have called me far worse), but I happen to think that three and a half billion motivated people is one big damn object in motion. And the only thing acting against that object is the friction caused by a small bunch of greedy, dumbass, screw-the-pooch, Ivy League pot stickers (the unbalanced force). I therefore assert that the unbalanced force (you know who you are, shame on you), will eventually be overwhelmed by the object in motion (three and a half billion people with pluck, aka pluckers), thus allowing the object in motion to continue its relentless journey forward, thriving and conniving until it is once again slowed down by other unbalanced forces, or a very large meteorite. Or a plague. Or fundamentalists with nukes. Or atmosphere-eating nanobots. Or a super volcano. Or Skynet. Or Cylons. See more »

The Hofstadter Isotope was another very funny episode of "The Big Bang Theory"
18 September 2009 | by (Baton Rouge, La.) – See all my reviews

This is another episode of "The Big Bang Theory" from last season that I taped during the original air date but only catching up with right now to prepare for the season premiere on Monday. Unfortunately, this one stopped in the middle because the VHS cassette was warped during that time. Fortunately, I read the full synopsis but still, I wished I had been able to see the whole thing. Anyway, it seems Sheldon doesn't like Thai food or maybe he's flabbergasted that it's "Anything Can Happen" Thursday instead of a traditional Thursday. The others just want to get out of their rut (though Sheldon calls it "consistency") so Howard suggests bar hopping. Sheldon, however, wins (because of his being Sheldon) and they go to the comic shop even though they went there last night. Penny encounters them and asks Sheldon to get her 13-year-old nephew a comic which gets Sheldon "correcting" her on the fact (for him) that a "comic" has funny animals. Not wanting to hear any more, Penny agrees to go with them. It's there they encounter Stuart, the store's owner who's also an artist. It also seems he likes Penny and she likewise since he has a cool sense of humor. Then next night when the nerds go back to tradition, Leonard, depressed about Stuart's luck with Penny (they're seen about to attend Stuart's art gallery), tells Howard he wants to go to the bars. I'll stop there and just say it was when Stuart and Sheldon, after arguing about Batman, find Penny asleep on her couch was when the tape stopped. Otherwise, this was a very funny episode I watched and as soon as I view the rest of it, I'll add my comments here. I've got several more second season eps to watch before the season premiere so until then... Update-8/18/10: Just watched the rest of this episode on my DVR. Hilarious with the way Howard and Leonard had trouble getting women while Raj got lucky after a few drinks...
