The Big Bang Theory season 12 episode 6 live stream: Watch online

Tonight on The Big Bang Theory, Halloween festivities run wild, including a costume choice gone wrong.

Wait, are we seeing two Sheldons? No, no — it’s just one Sheldon and one Wolowitz dressed as a Sheldon. That’s right, Big Bang Theory fans, we’ve got a Halloween episode! And of course, we’ll see goofy costumes and haunted hijinks.

From the looks of preview pics for the show, we see Sheldon in a Back to the Future getup, Leonard as Inspector Gadget, and Rajesh in some kind of… black gown with white lace? Okay. Sure.

Per CBS’ synopsis for tonight’s episode, there may be a bit of fun that goes too far?

"When Wolowitz dresses up as Sheldon for Halloween, Sheldon seeks retaliation at Leonard and Penny’s Halloween party. Also, Leonard is shocked that Penny doesn’t remember their first kiss."

Sheldon isn’t too happy with the idea of someone trying to be him — whether it’s trying to be as smart or as talented, or literally dressing up as him. Wolowitz’s idea to dress up as the boy wonder is pretty ingenious but may turn disastrous depending upon how upset Sheldon gets.

While a battle between those two is going down, Leonard is hurt to know Penny does not remember their first kiss. Our question for you Big Bang fans is… do you?
