the funniest thing i saw was...
not a prayer--but a short talk in the ministry school thing.
one particular afro-caribbean bro was very fond of over-running any talks he was given.
so--this particular evening--at the end of his 5 minutes--the bell sounded--but he carried on regardless, so--2 bell rings--still he carried on. at this point 2 bros got up on the stage--either side of him--took an arm each and frog marched him off the stage ( this had been pre arranged of course---but the bro and the audience weren't in on it )
yet--he still carried on with his delivery ! the audience were in stitches.
fortunately--the bro took it in good part. in fact--he was a truly lovely guy.
all this was 50 years ago.
