Fun

  1. Don’t take offense: I was only saying it as a fun.
  2. Don’t take offense: I was only saying it as a joke.
  3. Don’t take offense: I was only saying it in fun.
    Please correct and comment.
    Thanks.

[color=blue]All the colons are wrong; semicolons would be correct.

Canadian45,
When joke and fun are nouns, why we have to say ‘a joke’ and ‘fun’ without article?
Please explain the nuance of its grammar.
Thanks.

[color=blue]Jokes are countable; fun is not counntable.
