Claude takes a swing:

Ah, this makes sense being on a park bench! It appears to be a humorous saying in Bavarian/Austrian dialect that roughly translates to something like "when one has already laughed a lot, then one immediately has a better feeling." It's the kind of folksy wisdom you might find on a bench in Bavaria or Austria, suggesting that laughter makes you feel better or improves your mood.

Given this is quite an obscure dialectal inscription and I'm translating from a regional variant of German, while I'm confident about the general meaning relating to laughter and good feelings, some of the subtle nuances of the dialect might vary. The kind of saying would be very at home in a Bavarian beer garden or park setting where people gather to socialize and enjoy themselves.
