Penny and Sheldon in “The Terminator Decoupling”

[going through a box to find Sheldon's USB] Okay, I've got a box, but there's no key in here. Just letters.

[edgy] That's the wrong box. Put it back.

Oh, Sheldon, are these letters from your grandmother?

Don't read those letters!

Oh look! She calls you Moon Pie! That is so cute!

PUT DOWN THE LETTERS!
