That's the best story yet, mrs o!!!!! It's cracked me up but then that's boys for you.....
I had a wart on my big toe that wouldn't budge and I bought the stuff you freeze it off with. It's called Wartner, and it's more expensive (11 quid I think) but you only need one or maybe two treatments, and there are 20 applicators in there. AND, it's great fun!
You have a little holder, and a little spongy thing that slots onto it, and you have to press it onto the aerosol for so many seconds and it comes out steaming, but cold, and rigid. Then you nuke the bu$$er with it. One boy's got a verruca at the mo, and we zapped it a few days ago. In a day or so, it'll just fall off. It's fab stuff - you HAVE to have a go!!!
