Leonard, Sheldon, Howard and Raj all come to the conclusion that they have been so distracted ever since the arrival of the girls in their lives that they have not been able to focus their minds on the matter of just brainstorming on issues scientific. So they decide to have a boys weekend in to do that brainstorming. They encounter many problems along the way, the two biggest being what to focus their scientific priorities on, and how to stay focused on the task at hand and not get sidetracked by other distractions. While the boys are in, Penny, Amy and Bernadette decide to have a girls weekend away in Las Vegas. Once they arrive in Vegas, a situation with Penny leads to a role reversal where Penny ends up being the studious one, and Amy and Bernadette end up being the drunken party girls. Written by Huggo

Did You Know?


While white-boarding the "Back to the Future 2" timeline they have trouble with verbs. This parallels the Red Dwarf episode "Inquisitor" where Kryton reffers to conjugating verbs in the past impossible never tense. See more »


Sheldon erroneously defines Negative Reinforcement as "withdrawal of a positive stimulus". In fact, this is Negative Punishment, eg. denying a child his dessert because of a misbehaviour earlier in the day. Negative Reinforcement is the withdrawal of a NEGATIVE stimulus. For example, safe driving is "reinforced" by motorists' desire to avoid a traffic ticket . See more »

Crazy Credits


In my last vanity card I announced that I was quitting writing vanity cards. I was pretty firm about it. Didn't leave myself a lot of wiggle room. Not that I need any. Nothing's changed. I still feel like I made the right choice. Sure, I might have welcomed a groundswell of support for me to rethink my decision. I mean, I have been writing these things for 18 years. You'd think it would mean more to people. But no. The general reaction to my announcement was mild disappointment followed by a shrug. A literal shrug. I actually saw several pairs of shoulders lift earward an inch or two. No one sat me down and pleaded with me to reconsider. Nor was there a celebration on my having achieved such a singularly unnecessary, non-literary achievement. If anyone felt the urge to reminisce about a personal favorite vanity card out of the FOUR HUNDRED AND SIXTY-THREE that I've labored over, they certainly didn't bring it up with me. No, the best I could hope for was shoulder spasms. One "friend" politely asked me what I'm going to do with all the free time I'll have now. I said that I planned on cultivating bitterness. He looked to see if I was kidding. I shrugged. Which, if you haven't noticed, is how one elegantly ties up disparate threads in a meandering essay that is clearly destined to be underappreciated.
