Penny has just broken up with her latest boyfriend Mike who blogged about their sex life. Besides feeling embarrassed about the blog contents, she's angry with herself for what she sees as her poor choice in men, who all seem to fit into the same mold. After a few discussions between the two on her break-up and a few tantrums on Penny's part, Leonard finally asks Penny out on an official date. Penny agrees despite or perhaps because Leonard does not fit into that mold. Afterward, Penny has second thoughts about going on a date with Leonard and speaks to the one person who she feels can place the best perspective on it: Sheldon. Leonard too has second thoughts and speaks to his best friend, Sheldon. Using the analogy of Schrödinger's cat, Sheldon tells both individually that they have to risk opening the box to find out what's inside. Will either do so? Written by

Sheldon has fundamentally misunderstood the thought experiment of Schrödinger's cat. The vial of poison in the box was not set to activate at a random time, but in response to some quantum event. Also, Schrödinger was not proposing that it was actually true that the cat would be simultaneously alive and dead; he used the idea to show the absurdity of the existing view of quantum mechanics at the time.

[about the guy she just broke up with
He's moved on!
Wow! That was quick!
That's what I said to the girl with her legs wrapped around his neck.
In the opening scroll of the time line when it gets to 91,000 there is a mistake the dates read 93,000BC 92,000BC 91,0009C 90,000BC for some reason 91,000 is a 9c not a BC. See more
