Me and some friends tricked my little brother(10 years old)
We told him that the curtain took fire, and we had to put it out with the ice cream. then he asked "what about the second box?

"
earlier that day my friend tolf me that "The Longest Jorney: Dreamfall"(Probably the best Norwegian game in years ahead) was going to come next week instead of in the end of april (funny April is the name of one of the main characters in the game)
An old tricky swedish guy came and said he'd lost his dog, I asked where he last time saw it. Then he said it was a prank.
Later the same old guy told us that the candy was much cheaper on the gas station than in the shop Ica. Of corse we though it was an april fool spank, so we finished buying our sweets on Ica, later we found out that he told us the truth.
