Down here in Texas we do understand the meaning of the word OR. How come you don't?

If I were going to do this I would use some sort of magical electronic device which would, at the press of a button, make the sound of six 50's going 600 rounds per minute, or a 30 mm Gatling gun doing however many they do. Maybe a modified locomotive smoke device doing appropriate puffs of smoke. Come on, caps are so 20th Century!
