My bad.
Whilst searching for something on a shelf I found a whoopee cushion that had been confiscated from my son about 5 months ago.
He was stood right behind me and couldn't help giving it a squeeze.
PAAAAAARP!
Guffaws of childish laughter ensue (from him, not me!)
Anyway, I hand it to him thinking that after 5 minutes the novelty would wear off.Afterall, he is 5 months older.
45 minutes later and I'm still being dragged from my study into the lounge, instructed to sit down and act surprised at the trouser-rippling sound.
Blooming heck- he's here dragging me off again. Gotta go!
