Ahhhh.  The Fun Theory by Volkswagen.  Excellent!

Just for the FUN of it, I have begun--starting with my friends, students, and acquaintances--a worldwide campaign to substitute the word FUN for the word 'work' in all languages on earth.  As English speaking people have played with the possibilities--just for the fun of it--seems a mind-set change starts happening with smiles and laughter breaking out and contaigion often sets in.  A few samples:

 

Goodbye dear, I'm off to fun.

'Fraid I can't go with you.  I've got way too much fun on my plate, today.

Ooooo.  That's going to be a lot of hard fun.

That funs for me!

Hmmm.  Yes.  I think that'll fun real well in this situation.

You'll just have to get together and fun it out for yourselves, won't you?

Have you bought your July 4th firefuns yet? (in the U.S.)

We'll start in San Francisco and fun our way to New York.

Well!  That being the case, we'll have to increase our total funforce by 8%!

OK. Now your homefun assignment for tonight is.... (a learning experience that will be enjoyable to do??!! OMG!)

Have you kids finished your homefun, yet?

Do you know how your voice actually funs?

Get your fun done first, and then you can play!
