Doctor's appointment

I called the doctor this morning. "Yes?" he answered, almost half asleep. "Doctor, Doctor, I need help right away! When I pick stuff up, I get dizzy! When I play pool, I get dizzy! When I sip beer, I get dizzy! When I go up the stairs, I get dizzy! Even when I go down the stairs, I get dizzy! Help, help!"The doctor yawned and said, "Okay, I'll start working on the 15th of May. See you then.""15th of May?! But the holidays ended on the 6th! It's the 7th now! Everyone's starting to work! Why aren't you working?!""Because I'm dealing with a hangover!"
