Interesting stories.

[Lord Magus]

This group of friends (I can't remember all the specifics, our Dean told us this story at college years ago) were enjoying a reunion meal and drinks after not having seen each other in a long time. In fact, they were enjoying a whole BUNCH of drinks, not getting sloppy but definitely getting boisterous enough that the few other patrons in the small establishment knew what they were about. When time came to head out and pay the bill, these friends found they had drunk and eaten a lot more than they could afford. While they were scrabbling trying to put together money for the bill, and elderly gentleman who had been sitting a few tables away asks them if they have a pen or pencil he could borrow for a second. One of the friends obliges the old man, who then takes a napkin and the pen, scribbles something and signs the napkin, and hands both back to the young man who gave him the pen. The older man then tells the young gentleman to give the waiter the napkin and that should take care of the bill, and then the older man walks out.
The young fellow looks at the napkin and sees a quick sketch signed "Picasso".

Ends up the diner/restauraunt was one of his regular haunts, and apparently he enjoyed the thought of friends meeting up after a long seperation and didn't think their night should be spoiled becuase they enjoyed themselves too much.

(I may have messed up some of the specifics, but that's the general gist of the story)
