Hellblazer Issue 50, Remarkable Lives by Garth Ennis

King of Vampires: You seem very sure of yourself, you little mortal bastard, so I'll tell you what.... If you can tell me why your ordinary, piss-boring life is better than mine, you can walk out of here alive. If you can't, I'll cut your throat and drink my fill and leave you half alive forever.
John: Easy. Can you go for a walk in the park and hear the birds sing in the morning? Can you kiss a girl and know she loves you? Can you go out and get pissed with your mates? I can. And just so we're sure who's better off, why don't we sit here together and watch the sun come up in an hour or so?
