Fortunately (unfortunately?), that's about how Penny operates, too... without the bleeding to death and Hell, since her life was never exactly that exciting. And it's kind of silly to take death seriously once it's already happened and you're still running around and chatting.

"If you'd've been there for the musical number, you might rethink the coolness." Actually, everything prior to the death ray's explosion was pretty uncool. Just thinking about it encourages Penny to say, "Sure, I'd take another."
