From here on in, I've decided to make all trivial decisions with a throw of the dice, thus freeing up my mind to do what it does best, enlighten and amaze. Howard: So, what's for dinner? Howard: With Dungeons and Dragons dice? I have a date. I'm the one that introduced him to her. My mind is freed up to think about more important things. Penny: Uh, no, that's not it. Raj: What? She's deaf. Sheldon: Okay, get this. This is my friend Emily. Use it.
Plan: A: Penny; Q: Who sets up Raj on a date with Emily? A: his selective mutism; Q: What is no longer an issue for Emily? A: the Dungeons & Dragons dice; Q: What does Sheldon use to make trivial decisions? A: his mind; Q: What does Sheldon want to free up? Summary: Penny sets up Raj on a date with her deaf friend Emily, for whom his selective mutism is no longer an issue. Meanwhile, Sheldon decides to use the Dungeons & Dragons dice to help him make trivial decisions so that his mind is free for more important things. Although this allows him to get some important work done more efficiently, it also results in him eating things he would not normally eat, and making odd decisions.
