10. Toilet explosion
廁所爆炸

This walks the line in terms of harmlessness, but oh my G, it would scare the bejesus out of me! In fact, maybe it's the thought that counts with this stunt. I advise you to NOT actually do it, but just think about how scary it would be. POP! AHHHHHHHHHHHH!!! Yup, that's good enough.
這個惡作劇有點可怕，真的會嚇到別人。其實，我覺得單單有這個想法就夠了。我建議你不要真的做這種事。想一想這個玩笑的后果有多嚇人，就夠了。

Happy April Fool's, y'all! Just remember: always ask yourself, “What Would George Clooney Do?,” and keep in mind that the first rule of April Fools' Day is safety.
愚人節快樂！只要記住，永遠問問你自己“喬治·克魯尼會做什么？”并永遠記住愚人節的第一要義是安全。
