Morgan, Chuck and others in “Chuck Versus the Lethal Weapon”

I want to make sure that she [Anna] loves me for me and not... other things.

Are you crazy? What other things could she possibly be loving you for? I mean listen, buddy, you know that I love you, but you're lucky to have a girl in your life who loves you for you, even though you are in fact you. If you don't stop testing her, she's gonna choose to be with someone else. And then you will have realized, and unfortunately too late, that you lost the catch of a lifetime.

Counter point. She's not the catch of a lifetime. She's a scheming tart who will harvest your organs and sell them to the highest bidder.
