Here are various clips that we’ve managed to find from the The Big Bang Theory Comic-Con panel.

The Big Bang Theory has big finale plans in the works. Seriously. Don’t you see the Snuggie on Johnny Galecki (Leonard)? Crazy, right?

The guys are setting out on a summer adventure to the North Pole and leaving their girl Penny behind. You might be asking yourselves how they could do such a thing, but Jim Parsons (Sheldon) said it best when we caught up with him and the rest of the cast on the set.

“I make them an offer they can’t refuse,” teased Jim. “Not that Sheldon’s the Godfather, although I guess in some ways he is the scientific Godfather.”

Keep reading for more on a Leonard-Penny hookup and most importantly, which one of these genius remembered to pack that toasty Snuggie…

Why the North Pole? “Sheldon is invited to go on a National Science Foundation expedition to the arctic, and we go along as his crew,” said Johnny. “There’s a lot of bracing for three months on an ice cube in a hut—with Sheldon.” Sounds kooky.

And the Snuggie? It’s just a thoughtful bon voyage gift from Penny to Leonard.

Speaking of the twosome, what does this mean for possible romance? Johnny tells us, “Leonard and Penny have to say goodbye for the summer, which blindsides them in a way that they didn’t foresee.” Kaley Cuoco (Penny) agrees. “The whole episode Penny’s acting very aloof. We don’t know until the last line of the episode exactly how she feels. She didn’t realize how much she didn’t want him to leave.”

What about life after the North Pole? Kunal Nayyar (Raj) and Simon Helberg (Wolowitz) have some ideas. Kunal’s suggestions? “We’re all going to come back with beards and bloodshot eyes. Raj has become 300 pounds. We’re all going to look like Joaquin Phoenix.” And Simon? “We’ll be wild animals when we get back. Sheldon should have a handlebar moustache, too.”

Kaley’s hoping for some new meat too. “Four new guys, all living with her. Or they should come back and she’s met someone and it is semi-serious.” We’d definitely watch that show!

Now that The Big Bang Theory is coming back for two more seasons, are you as excited as we are to see where things go with Leonard and Penny? What do you think about this North Pole craziness? Let us know in the comments below.
