Ok, several things to nitpick here today so let's get started.
The raygun: Looks pretty terrible with that mini-cymbal for a muzzle. I don't know how it fit into Scratch's holster earlier.
Panel 3: What Shecky's saying isn't especially dramatic, so the silhouettes are unnecessary and feel out of place in the middle of the strip.
Panel 4: Giant forearms of doom!
Panel 6: I guess it is a magical bar. Would be nice if we could actually see some background characters (or a background for that matter) that drove that point home.
Panel 8: The goggles, they do nothing! (for me).
I actually chuckled at the giant poofing out of existence. I think if Kurtz erased the barrier between the last two panels and got rid of Scratch's "kick in the nuts" line, we'd actually have a decent punchline.
