Ahahahaha I thought that story was hilarious....don't get so stressed over something so very funny! I bet the kid who did it is really cool..

Apple sludge dries ,no?

You will ofcoarse have to get him back!! Infact ...start a campaign against him...some old skool classics include;

Write a love letter to the teacher "from" him ...leave it on the desk and get someone else to find it before hand and "discover" it!

Leave and chopped onion...some chopped garlic and some "week old" mik either in his bag[prefered] or in his jacket pocket and hood!

Start the "Herpies" rumour...Simply tell everyone alive that he has Herpies and pretty soon it will spread like wildfire and no doubt stick with him as an uncomfortable nick-name for years to come!

If he catches up with you and it "goes to blows"...then "Cunch his Punt in"!!
