It's the 150th episode of 'Family Guy' (Sun., 9PM ET on Fox). On the very special episode, Brian and Stewie Griffin end up trapped together in a bank vault. Spending so much enforced time together makes the two characters realize they don't really hate each other after all. In fact, they might kind of love one another.

Brian reveals that he keeps a gun locked in the bank safe-deposit box -- in case he ever wants to commit suicide. He also confesses to lacking a sense of purpose in his life. "I've tried to find meaning in my life, and I just -- I just can't." Which forces Stewie to admit that he'd really miss Brian if he died. "You're my only friend, Brian," he says. 'If I didn't have you, I'd be lost."

Aw. It's a surprisingly touching episode of 'Family Guy.' In the end, Stewie finally confesses that he does love Brian. Though not in a weird way, he quickly adds.
