Doing circumcision the hard way

Circumcision is a practice in which the foreskin is removed, and is prevalent in many religions and cultures. At the same time, the skin is very sensitive at that point, and the removal needs to be done with care. The removal is normally done early on when the person is a young boy, and with due care. So, how do you account for this chap, who wanted to do the circumcision using nail clippers, without any form for anesthesia ? Maybe, a few drinks were enough to get the person to try out this new way of doing circumcision (link to article):

A medic at Lister Hospital in Stevenage, Hertfordshire, has advised men against attempting DIY circumcision with nail clippers, after a young man who'd decided this was the best way to go roundhead was admitted for emergency treatment.
Hinting at what had provoked the patient to treat his foreskin in such a cavalier fashion, the medic concluded: "Using a pair of nail clippers must have caused excruciating pain, even if he had had a few drinks beforehand."

Seems fairly obvious advice ! Doing this by yourself in such a sensitive body location would surely have been very painful.
