Knowledge!
I feel like a mad scientist in his lab listening to this. White lab coat, vials of green being dripped into other beakers with swirly tubes of various chems boiling and perking.
Near the middle the potion is complete! I gotta go try it on my first subject! Frank gets up and starts doin the robot. He goes berserk and destroys the lab! He's on the loose! Is it my problem? No. I'm a mad scientist, this is right up my alley. Content that my potion works, I begin testing on other animals. Near the end a gleam in my eye as I cackle loudly and transform into a bat...flying away into the night.
