Okay, similar questions to this have been asked before, but not about the particular short story I am trying to find.
It was in an anthology of short sci fi stories, possibly award winning ones or at least someone's compilation of favourites. (I think)
It was a long time ago, maybe 1970s or 80s, so the story could date back to even the 1960s for all I know, but probably the 1970s.
It was the funniest story about time travel where a person meets incarnations of himself, that I have ever read. It was either derivative of 'By His Bootstraps' or the other way around, but my recollection is that this story was funnier.
Maybe my memory is playing tricks on me and it WAS 'By His Bootsraps', but I am almost certain that it wasn't, because when I read that recently it seemed unfamiliar and not as funny.
In the one I am trying to recall, the guy is also bemused and irritated by the behaviour of other incarnations of himself, like the Heinlen story, but the repartee between versions of himself and his extreme frustration is much more hilarious.
I have a vague recollection that he is in a spaceship during the story, but not absolutely sure. There seemed to be a lot of clambering around, ladders, bulkheads, etc, unlike the Heinlen story.
I'm almost certain it isn't any of the commonly suggested stories and I'm quite sure it wasn't a short film where he shoots his older self, or a full length novel. Someone will have read it and (un)remembered it fondly like me, I feel sure!
