Toilet jokes

Well I suppose I could only be immune to it for so long. As I had the good sense to give birth to a daughter I have probably avoided it for a little longer but finally they have caught up with me...drum roll please...toilet jokes.
Wee, poo and fart jokes and words now seem to amuse my previously delicate daughter (well maybe I am exaggerating on the delicate just a little!!)
Though it is hard to chastise when I am playing along with the joke.
The other night on the way home Kelly had found an old balloon in the car (amidst her assortment of hair-ties, pens, textas, lolly wrappers, don't even go there). She was blowing it up and letting the air out, much like a whoopee cushion. Well of course I went along with the joke and the "Oh Kelly, you're disgusting" only encouraged her further.
Then in exactly my words and tone of voice, she announces "Oooo Mum I've got pains" and lets the balloon whistle out a beauty.
Well I laughed so hard that I under steered into the roundabout, narrowly missing the gutter.
A good fart joke still funny at 41?? Baaad Mother :-D
