Apparently there's a tradition/running joke in Prague that came out of a novel by a famous (though inexplicably lost to history) Czech novelist who once mused that people can be divided into 3 categories:
1) Those who would pass by a plate of stale donuts and think nothing of it
2) Those who would pass by a plate of stale donuts and consider throwing them at passers-by
3) Those who would pass by a plate of stale donuts and actually throw them at passers-by
In honor of this all-encompassing personality test, the Imperial Cafe, an upscale Prague eatery, offers an additional menu item: a plate of rock-hard stale creampuffs and the tacit permission to pelt your fellow patrons. Just remember that in doing so you've not only united the populace against you, you've also armed them.
