Robin is about to write a song. It is going to be in the vein of Bob Marley’s classic “I shot the sheriff but I did not shoot the deputy” and is going to be like “I cut the penis, but I did not cut the testicles”.
This man has got balls!
Robin is going to collect information about other men who castrated themselves and hopes to get further inspiration.
