The Big Bang Theory, Season 8

[The group are preparing Stuart's Comic Book Store for its reopening. It is a tense affair, as Penny has found out that Amy and Sheldon have been testing Chimpanzee puzzles on her, Howard has discovered that his mother, before going to visit her sister in Florida, had loaned Stuart some of her furniture for his store, and Sheldon, having found out that Amy provided Kripke with mathematical assistance, is trying to grasp the concept of letting things go. Leonard is conversing with Penny]

Leonard:
I can't believe they did that.

Penny:
I know, it's so insulting. At one point, they had me figure out how to get a banana out of a puzzle box!

Leonard:
Wait... Sheldon gave me a banana in a puzzle box. He was testing me too!

Penny:
Unbelievable.

Leonard:
And how could a chimp even solve that? That was impossible.

Penny:
Really? You couldn't get it out?

[Amy and Sheldon knock on the door. Raj lets them in, and Sheldon thanks him. Leonard and Penny get up and advance on them at once]

Amy:
Wow, the store looks great -

Leonard:
So you were testing us both? What is the matter with you?

Penny:
What's the matter with them is they think they're so smart, they don't care if they hurt other people's feelings!

Amy:
That isn't true!

Sheldon:
[concurrently] That sounds like us. [Amy looks at him in irritation] I still don't understand why you're upset. You solved every puzzle faster than all of the chimps.

Amy:
Well, except Barnabus, but he was on Adderall.
