Genuine story from my boss. A couple of years ago, he was living with his dad when a letter from the doctor’s arrived addressed to “Mr Anderson” (for the same of argument – names changed to protect the innocent).
Obviously with them being father and son, they’re both Mr Anderson. Mr Anderson Senior (72 years of age) opened the letter and read that it was about an appointment. He duly noted the date and went to attend.
He arrived at the clinic, sat down and waited. After a while, a nurse called his name and asked him to go into a particular room to see the doctor. Upon arrival he sat himself down and the doctor started an informal chat.
“Before we go any further, Mr Anderson, we need to ask a few basic questions.”
He nods. Fine.
“First of all… how long have you been considering having the vasectomy?”
Apparently it took them a week to clean the burnt rubber from his plimsoles off the floor.

ha ha, very good.
