Lotus had eatin' some shrooms earlier and found himself a cave with the intent of a spiritual experience.
"You're late. I started taking the Fourier Transform of these rocks without you," the Fourier Transform Wizard said.
"Well, how do you take the Fourier Transform of a rock?" Lotus asked.
"The same way you take one of a cat," FT replied.
"Are you crazy or drugged or just in my imagination?"
"Look within yourself, you know the answer."
A bright flash occurred in the cave, and Lotus found himself in the frequency space.
