Freeze Ray T-Shirt
This is the one. Stops time. Tell your friends.
When Billy-buddy a.k.a. Doctor Horrible needed to defeat his arch-nemesis, Captain Hammer, he developed his Freeze Ray. Not an ice-beam! That's all Johnny Snow! This one stops time. Yeah. Just need to work on the warm-up cycle time...
The Freeze-Ray is almost up. This is the one. Stops time. Freeze-Ray. Tell your friends. - Doctor Horrible
Doctor Horrible's arch nemesis is Captain Hammer (no matter what Johnny Snow says). Captain Hammer is strong, fast, and tough - three attributes that describe Doctor Horrible not at all. Sure, he's got brains to spare, but it's hard to think when you're getting punched repeatedly in the face with a car. So, to level the playing field a bit, Doctor Horrible has to get the jump on old Cheesy-on-the-inside by zapping him with his patented Freeze-Ray.
No! It's not an ice-beam! That's all Johnny Snow! This is the one. Freeze-Ray. Stops time. Tell your friends. He just has to make sure he plans adequately for the warm-up phase of the firing sequence. Also, even though wonderflonium is... well, wonderful, it can only power the temporal field for about two-minutes and ten seconds, so he should keep the monologuing and dramatic solos to a minimum.
