You could be in huge trouble for prank call on your teacher.
This is what I'm gonna do for a late April Fools: If your teacher CAN'T STAND snakes, get a fake one (you can easily buy them at Walmart in the toy section) and hide it near, in, or under his/her desk. Warning: This is NOT a prank for a teacher with a bad sense of humor. The following is also not a good idea for those teachers. This is pretty lame, but it can be for your classmates too. Get a bag of Oreos and scrape the frosting out of the middle. Refill the middle with toothpaste and make the packaging look new. Also, if your teacher is a HUGE fan of chocolate, tie a string to his/her favorite chocolate and when he/she is about to grab it, yank the string. That's all I have. Good luck. ;-)
no No there was a guy named Isaiah Michael Jackson who thought it would be a good idea to dress as a Gorilla and pull a prank by snactching a kid.
give it to all of your pets or you could give it to your teacher via their coffee
