These exist elsewhere too, but nowhere I've seen as many dedications on park benches as in the UK. This is one of my favourites:

"Nina Theresa Jenkinson 4th of May 1959 - 5th May 2017 She took pleasure in annoying the fisherman by feeding the ducks."

It perfectly encompasses the best of British passive-aggressiveness - the bench is near a private fishing-pond inside Crystal Palace Park (which is public). Couldn't do anything about a nice pond being walled off in the middle of the park, but she could sabotage the fishing by getting the ducks all worked up...
