A man comes to the doctor and asks for a vasectomy.
“What, a vasectomy, right now?” asks the doctor baffled. “Yes, i’m a bit in a hurry, my wife is waiting, we want to go shopping and to the movies afterwards and she found it a good idea to get a vasectomy first.” The doctor shrugs and says “As you like it, come in then.” Said and done, and when the man comes back to his wife she’s asking “All ok with you, did it go well, did it hurt?” “Not at all” the men replies “i had a anesthesia of course.” “What, anesthesia for a vaccination?!” the wife is confused. The man slaps his forehead and shouts “Vaccination!”
