"Hello villains! Are you tired of having to reload your guns during killing sprees? Well no more! Introducing the new Pocket Dimension Where You Can Keep More Guns! Just hide this device under your edgy overcoat and viola! Dr Flug, if you could give us a demonstration…"
"O-oh, you want me to wear the device?"
"No, I want you to stand still and let me shoot you. So I can then get more guns. So I can shoot you some more."
