A chicken and egg are in bed together.

The chicken has his arms/wings folded back behind his head.

Big grin on his face and puffing away on a cigarette.

Meanwhile the egg is miffed, rolled up in the duvet and not very happy.

The egg turns to the chicken and says "Well, I guess we answered THAT question!"

That is one of my best jokes and I am a bit of raconteur when I get rolling though with mixed success. I really enjoy humour that has that twist in it and Spike Milligan is one of my heroes with the misdirection of simple thought. I recall he was introduced on the Goon Show as "that well known typing error, Spike Milligna" and you had to be quick to catch everything he packed into those scripts.

Writing with humour is a fantastic way of engaging your readers but beware of too much. Remember your target audience as not everyone gets the joke and some may be positively offended - most women I have cracked the joke above too have laughed and made some come back about "How true!" but that does not mean to say everyone will.

I wrote a dating book some time ago, and filled it with crass, male humour which my commissioning client thought was great. The book was deliberately written to be mildly offensive to any woman who read it but I was surprised at how offensive I felt it all was. Some things can be very funny in a personal context but not in public, and what is not funny to you will appeal to someone else.
