lead in his head

Presumed lead poisoning, causing acts of extreme blankness.

"Maybe the lead in his head will gently bend the branch down to the ground before he finds out what it takes to make it to heaven."

Putting Lead In Your Pencil 

From the Journal Of The Royal Society Of Medicine. To insert a foreign object into ones Urethra for sexual pleasure especially during masturbation. Damn Doctors U got scary black humour.

A 62-year-old man was referred to us from a nursing home by staff concerned that he had apparently passed a small household (AAA size) battery per urethra. The patient was in pain with difficulty in passing urine. Relevant in his past medical history was that one year previously we had endoscopically removed a pen lid from his bulbar urethra.

An X-ray of his pelvis revealed what appeared to be two dense foreign bodies in his urethra. Urethroscopy revealed two AAA size household batteries lodged in his bulbar urethra. On further questioning at discharge, the patient admitted to inserting three AAA sized batteries into his urethra for sexual gratification during masturbation four weeks earlier. The Doctors decided to call it putting lead in your pencil, the age old euphemism for sexual vigour and erections.
