If you’re a Big Bang Theory fan and for some reason you’ve missed the promo for tonight’s episode, they’re dealing with a big decision.

The promo suggests that all of the main characters are going to have to make some big decision and it’s all going to unfold in 22 minutes. While it’s unclear what Penny and Leonard’s decision is, or what Raj is contemplating, it’s the decision that Sheldon must make that takes the cake.

The promo cuts to Sheldon and Amy Farrah Fowler in the video game section of a big box retailer. Yes Sheldon is contemplating the big decision, Xbox One or PlayStation 4. Sheldon’s internal conflict begins earlier in the episode where you see him researching video game consoles on the computer. At some point he also hears that it’s better to make a big decision like this on a full bladder.

As you can imagine Sheldon and Amy Farrah Fowler head to the store and Sheldon has to go to the bathroom, which can only add more great comedy from character actor and comedian Jim Parsons.

Of course the promo leaves you in a cliffhanger wondering does Sheldon opt for the Xbox One or the Playstation 4. Over the previous seasons viewers find out that Leonard and Sheldon have owned just about every game system so there’s really no indication as to where his decision may be.

You’ll just have to watch it tonight. Check your local listings.
