Perception Jokes

(sung to the tune of Three Blind Mice)
Three rodents with defective visual perception,
three rodents with defective visual perception.
Visualize how they perambulate,
Visualize how they perambulate.
They all perambulated after the agriculturalist's spouse,
she severed their spinal columns with a kitchen utensil.
Have you ever seen such a spectacle in your existence,
as three rodents with defective visual perception?
