If you’re anything like me you’ll have had really boring teachers at school. They were dull, serious, and not willing to have anything approaching banter.

Which is why this video of a teacher pranking his students is so satisfying. And the reason it has recently gone viral.

This teacher gives his students a spelling test full of made-up words. The students don’t know they’re made up though, and do their best to answer correctly.

At the end he reveals the whole thing to be an April Fools’ Day prank. Even though, as the kids point out, it isn’t actually April.
