Raj: Hey, an animal can be both sacred and delicious.

Oh, it's okay. I have no morals and I'm desperately lonely. I'll be the other man if you want a little something-something on the side.

Howard: If I may, he has so little self-respect and is so desperate for the smallest crumb of affection, she could literally sleep with his own father in his own bed and post the video to YouTube, and he'd still buy her flowers and ask her to be his bride.
