Roger: "But how do you use all these weapons without any fingers?"
Dweeble: "WHAT?! Are you mocking me?!"
Roger: "No, of course not! Just curious."
Dweeble: "Okay... I'll tell, but if I see even a twitch that looks like ye're laughin, I'll blast yer head off!"
Roger: "Yes, but how..."
Dweeble: "Finish that question and I'll... I'll... slap you!"
Roger: "Sorry about that. So... what's the story?"
Dweeble: "Aye, I don't have any fingers to use the weapons. But if I could, Vohaul wouldn't let me anywhere near his base with all this stuff."
Roger: "I see."
