Some half decent jokes in there Jason but nearly all of them need work, for instance;
"I'm not saying my wife's a bad cook but, she made fairy cakes with washing up liquid the other day."
The punch needs to be at the end of the joke so it should be;
"I'm not saying my wife's a bad cook but, the other day she made fairy cakes with washing up liquid."
Also I'd change the "with" to "using" so it becomes "she made fairy cakes using washing up liquid".
Oh and what is "Finning"?
