A man takes his sick Chihuahua to the veterinarian. They’re immediately taken back to a room.
Soon, a Labrador walks in, sniffs the Chihuahua for 10 minutes and leaves. Then a cat comes in, stares at the Chihuahua for 10 minutes and leaves. Finally, the doctor
comes in, prescribes some medicine and hands the man a $250 bill.
“This must be a mistake,” the man says. “I’ve been here only 20 minutes!”
“No mistake,” the doctor says. “It’s $100 for the lab test, $100 for the cat scan and $50 for the medicine.”
