Fun is uncountable and joke is countable and therefore the word fun never takes an indefinite article a or an.  You can say “he made a joke" but not “he made a fun".  

Fun means entertainment or pleasure or something that gives entertainment or pleasure. Joke refers to what you tell to make other people laugh.  Joke is normally concerned with process of making pleasure whereas fun is concerned with process of receiving pleasure.  You can tell a joke and others can have fun.

The phrases generally used in the case of joke are “tell/make/ crack/play jokes", dirty jokes (sexy jokes), get the joke, get beyond a joke, take a joke and “only did it as a joke".

1.We were just cracking jokes on his dressing.
2.I don’t get the joke he made. (=don’t understand)  What does it mean?
3.Stop it! Your teasing is getting beyond a joke. (=crossing the limit)
4.Why are you serious? The trouble with you is you can’t take a joke. (=You couldn’t take it easy)
5.Why are you weeping? I only did it as a joke.

Similarly you can use the word “fun” as in the following expressions:
1.Come on! It’s time to have fun.
2.I am learning French just for fun. (Not for job or with any serious purpose)
3.I like his sense of humour.  His whole speech is full of fun, isn’t it?
4.If you talk like this, you will become a figure of fun. (= a laughing stock)
5.Don’t make fun of your higher officials. (= Make others laugh at them in unkind way.)

Just for fun!
