7. Turn your coworker's world upside down

　　把你同事的电脑桌面倒过来

　　This one's not a show-stopper, but it is super easy, and tame enough for almost any office. When your (hopefully good-natured) coworker heads off for a bathroom break, hit Ctrl+Alt+Down Arrow to flip the screen on his or her PC upside down. The antidote is simple: Ctrl+Alt+Up Arrow… but it's probably going to take them a frustrated (read: funny) five minutes to figure that out。

　　这个不是那么好笑，但容易操作，而且可以在任何办公场所使用。趁你的同事去厕所的时候，同时按住Ctrl+Alt+向下的箭头就能将电脑屏幕上的内容颠倒过来……返回操作就是Ctrl+Alt+向上的箭头，不过他们可能要花5分钟才能将屏幕调回来。

　8. Brown E's

　　巧克力布朗尼(棕色的E)

　　If you like puns and tricking hungry, innocent tummies with the promise of delicious fudgy chocolate for the bait-and-switch of construction paper, then this will be right up your alley — a pan of brownies on the outside with inedible brown letter E's on the inside! No oven required to bake up this April Fool's trick, but you may have a hangry mob on your hands once your prank is revealed… don't say I didn't warn you!

　　如果你喜欢双关语，又乐于用美味的巧克力蛋糕做诱饵整一整身边的吃货，这一招绝对适合你。炮制一盘外包锡纸上写有巧克力布朗尼字样的假甜点，里面装着的却是棕色纸剪出来的E！做这款“蛋糕”自然用不到烤箱，不过，真相败露后，你可能会被一群又气又饿的吃货围攻，别怪我没提醒你哦！

9. Theoretical wet floor

　　小心地滑

　　Guys, it's H2O the molecular model, not H2O the actual water! LOL, now THAT is a doozy!!! *Sighs, shrugs shoulders* To be fair, I'm not the target demo, but if you've got access to the right equipment and a brainy, captive audience, then I predict you'll make a splash with this April Fool's Day prank. Here's looking at you, nerds。

　　同学们，洒在地上的不是真正的水，而是构成水的H2O水分子模型！哈哈哈，这一招太出彩了！旁边一堆人耸肩，叹息。。。不过，我不是这个玩笑的目标人群，如果你手里有合适的材料，又有一群知识渊博的观众，这个点子肯定能在愚人节大放异彩。哈哈，看你们的了。

10. Toilet explosion

厕所爆炸

　　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。

　　这个恶作剧有点可怕，真的会吓到别人。其实，我觉得单单有这个想法就够了。我建议你不要真的做这种事。想一想这个玩笑的后果有多吓人，就够了。

　　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。

　　愚人节快乐！只要记住，永远问问你自己“乔治·克鲁尼会做什么？”并永远记住愚人节的第一要义是安全。
