bbt halloween cbs 'The Big Bang Theory': Sheldon's scared while Leonard is terrifiedHalloween is in the air. And if there’s anyone better to offer trick-or-treat pranks than the four nerds from “The Big Bang Theory,” we’re out of ideas.

After Howard (Simon Helberg), Leonard (Johnny Galecki) and Raj (Kunal Nayyar) scare the photons out of Sheldon (Jim Parsons) with an elaborate trick, Dr. Cooper spends the entire episode trying to get even. However, it turns out that he’s not quite the merry prankster he wants to be.

But the main story this week is Leonard. He meets an attractive woman named Alice (Courtney Ford) at the comic book store. They hit it off immediately, but there’s that little problem – his girlfriend Priya.

So the morally conflicted Leonard seeks advice on what to do. First he asks his his ex-girlfriend Penny (bad idea) and then Sheldon (worse idea).

At the end, Leonard does the right thing. Of course this depends on what your concept of the “right thing” is, but we shan’t spoil the surprise. Leonard also gets his own surprise from Priya.

As for Sheldon, he finally exacts his revenge for the earlier scare, just not in the way you might think and perhaps at the least opportune time.

On a scale of 1-to-Pi, this episode deserves a square root of eight. The stories were a vast improvement over last week, and Leonard showed his true character. Plus we got a little bit of a cliffhanger. The one problem was not enough Howard. There can never be enough Howard.
