I have to say that my dad is one for loud, loud farts, and then blames it on the insulin he injects!
Generally, we've managed to teach the children that it's okay in our own home, but not around mum, or strangers, as it could be considered rude....
Meanwhile, my ds (aged 6), having been disappointed in not being given his own whoopee cushion (long story), goes and invents one.
He'd bought a duck whistle with pocket money last year, and improvised by putting a balloon over the mouthpiece, blowing up the balloon by blowing air in the wrong way (holding the end of the balloon to stop air coming back out) and then let the air out.
The noise was incredible and hysterically funny. the nearest I can describe this is perhaps a duck on steroids
I am weeping tears of laughter just thinking about it.
And the best bit is that my brother was here with his boys, who were equally entranced by the improvisation. With my brother being less than impressed, I am rather tempted to buy a duck whictle and a packet of balloons and post to said nephews
