I love all the great dialogue in the game, so I've been playing it again to try and get all the lines. Apparently, Manny will try to pick up Meche only when they're locked in the safe together. I've also discovered that he does a salute with the soldier's arm when standing right at the entrance to the catacombs. But I can't find out where Manny says "You can't hide from the Grim Reaper. Especially when he's got a gun."
Any other good quotes I'm missing out on?

You could proceed in this thread (http://www.lucasforums.com/showthread.php?threadid=95091), and post all those quotes or some events that happens to be funny. ;)
