Okay, not that I like Buffy or Angel, but I have to admit, without it (albeit through Dragonball Z Abridged), I wouldn't have my best conversation stopper.
Wanna know what that is?
I've lived for over 2000 years, and not all of them were good ones. I've made many mistakes. And it's about time I did something about that.
