On the face of it, this simpleton dog seller from Prague has nothing going for him. Even the dogs he sells are mongrels, made up to look like pedigrees (with fake certification, naturally).
As the story progresses, you find he is not only intelligent, but uses dumb ignorance to get his way. From almost starting a riot in Wenceslas Square, to being lost by his officer in a card game, to being captured by his own troops, the scrapes Hasek creates for his hero will make you laugh out loud.
Don't be scared if you think the setting is outdated, the footnotes are excellent in explaining the context. I guarantee you will recognise many of the characters in people you have met.
One word of warning though. Hasek died while writing this masterpiece. Literally in mid paragraph. Its frustrating, but makes you wonder, what if....
