Amy rocks Sheldon’s world in a new clip from The Big Bang Theory season 7, episode 4, “The Raiders Minimization.”

The Big Bang Theory season 7, episode 4 airs tomorrow night on CBS. The episode, titled “The Raiders Minimization,” focuses on a feud that develops between Sheldon and his yes-really girlfriend Amy after an attempt at bonding goes badly awry.

Check out how it all goes downhill in this new clip from “The Raiders Minimization.” (Spoiler alert: Raiders are involved.)

In the sneak peek, Amy is unimpressed by Indiana Jones and the Raiders of the Lost Ark, which Sheldon screens for her. (Perhaps naively, she assumed that the bonding Sheldon intended was to be of a more, shall we say, physical nature.) Amy admits that the movie has serious story flaws, the very idea of which Sheldon finds hilarious.

Unfortunately for Sheldon (and for movie fans), Amy points out an issue with Raiders of the Lost Ark that leaves her boyfriend’s jaw dropped like a guy trying to out-drink Marion Ravenwood.

It looks like the issue is only going to escalate from that point onward in The Big Bang Theory season 7, episode 4. The official episode summary for “The Raiders Minimization” says:

Sheldon seeks revenge after Amy ruins one of his favorite movies. Meanwhile, Leonard discovers a way to get Penny to do anything, and Raj and Stuart create online dating profiles.

Christine Baranski will reprise her role as Leonard’s terrifyingly scientific mother in “The Raiders Minimization,” and Kevin Sussman will return as the long-suffering comic book store owner Stewart.

Check out the episode promo and still photos from The Big Bang Theory season 7, episode 4 for a better look at the madness that will follow Sheldon’s ill-fated viewing party… and a few shots of Raj and Stewart taking what looks like bizarre selfies.

The Big Bang Theory season 7, episode 4, “The Raiders Minimization” will air tomorrow night at 8:00 p.m. on CBS.
