LOL, I have been watching those videos and there great! How about a Viagra, Enzyte or extendz one? I know you can't show it actually working but you could do this.

Doesn't work: Female Co-Caster looks normal.

Does work: Female Co-Caster's hair is messed up, clothes dishelved, smeared makeup and hickey's all over?

Or how about the Grab-it Screw remover?
You can try it on sports cars and bank safes?

Just some Ideas, keep the videos coming.
