A veterinarian was feeling ill and went to see her doctor. The doctor asked her all the usual questions, about symptoms, how long had they been occurring, etc., when she interrupted him: "Hey look, I'm a vet. I don't need to ask my patients these kind of questions: I can tell what's wrong just by looking. Why can't you?"
The doctor nodded, looked her up and down, wrote out a prescription, and handed it to her and said, "There you are. Of course, if that doesn't work, we'll have to have you put down."
A nice, calm and respectable lady went into the pharmacy, walked up to the pharmacist, looked straight into his eyes, and said, "I would like to buy some cyanide."
The pharmacist asked: "Why in the world do you need cyanide?"
The lady replied: "I need it to poison my husband."
The pharmacist's eyes got big and he explained, "Lord have mercy! I can't give you cyanide to kill your husband, that's against the law? I'll lose my licence! They'll throw both of us in jail! All kinds of bad things will happen. Absolutely not! You cannot have any cyanide!"
The lady reached into her purse and pulled out a picture of her husband in bed with the pharmacist's wife.
The pharmacist looked at the picture and replied: "You didn't tell me you had a prescription!"
