No freakin' kidding. Let me guess, you went to the doctor for the sinus infection. During the exam, you brightly mention "Oh, hey, I'm going to Japan the day after tomorrow!"
The doctor, pulling off his glove and telling you you can sit down again, clears his throat. "That's not... entirely accurate."
"But I've been looking forward to this trip!" You protest, pausing only to blow your nose. "Also, this is a sinus infection, right? Why the prostate exam?"
"Oh, I just like to stay in practice. Anywho, with that sinus infection, you could injure yourself in the lower cabin pressure of the airplane. We don't like to advertise it, but your head could actually explode."
"Gosh!" you exclaim, taking off the nipple clamp, "that sounds like it would really hurt!"
"No problem, just send your girlfriend in your place. Here, you can tell her yourself. Nurse! Get in here, Ack-Ack has news for you. And go ahead and tell your two o'clock to cancel, a paddling can be rescheduled, but YOU have some packing to do!"
