A little less amusing... During my flight training another student landed at the wrong airfield. He should be landing at a quiet uncontrolled airfield, made all the right calls (at the wrong frequency), landed, vacated and then sees a huge control tower blinking various colors lights at him. Oops.
Instead of taxiing to the tower, he panicked, whipped the aircraft around back onto the runway and took off again. Without looking at lights, without checking final, without clearance (obviously).
Rumour has it that a 737 on short final was not amused about having to go around.
On the way back, he called an en-route frequency for Flight Following. Instead of FF however, he got something along the lines of "Sonny, you've got pen & paper handy? Here's a telephone number I want you to call as soon as you've landed."
In the end I think he got off with some "remedial training" and apologies from both him and the school. But it was a tense few hours after he landed back at base.
