L 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.”
