You can order a wake-up-call for yourself or for your friends through the website www.fokkiefoon.be (Dutch) and www.fakeservice.be (French). You can choose the dyslectic message people will hear when waked up.
Looking at the database, we see most people want to get their friends out of bed around six in the morning. Quite a prank. Since many people are jetlagged during the whole week, the service will be available until Friday 4th of April. Enjoy.
