A note to teachers everywhere: if you really want to annoy your students, pull an April Fools' prank three-days early. The results are so worth it.

Case in point, one Joey Dombrowski, a fourth-grade teacher in the U.S. who treated his class of 10-year-olds to a spelling test like no other.

Full of made-up words like 'Speekuzslmn' and 'Slipert', the kids get more and more infuriated as the answers are revealed, and the final explosion of rage when they find out it's all a prank is just dynamite.
