"Expensive doctor!" joke

Santa goes to consult a famous specialist about his medical problem.
"How much do I owe you?"
"My fee is Rs 500," replies the physician.
"Five hundred? That's impossible."
"In your case," the doctor replies, "I suppose I could adjust my fee to Rs 300."
"Three hundred for one visit? Ridiculous."
"Well, then, could you afford Two hundred?"
"Who has so much money?"
"Look," replies the doctor, growing irritated, "Just give me Fifty rupees and be gone."
"I can give you Twenty rupees only." says Santa, "Take it or leave it."
"I don't understand you," says the doctor. "Why did you come to the most expensive doctor in This Friggin' town?"
"Listen, Doctor," says Santa. "When it comes to my health, nothing is too expensive."
