Practical Joke Time

[Jamie.]

Well it was the mrs' brothers birthday on Wednesday and I'd been saving These bad boys for a time just like this!

We put the fake one inside a birthday card from my son and a real scratch card in the card from me and the mrs.
Didn't get to see his reaction as he took the cards home but he genuinely believed he'd won until he read the back of the card Which Read something along the lines of "to claim your winnings simply contact Santa claus or the tooth fairy.....etc"

It's cruel but cruel is sometimes funny!!
