Best april fools joke?

April fools day is comming: What can you come up with for the BEST APRIL FOOLS JOKE?

I dont no bout the best but its always fun to cover a cardboard box w/ frosting and tell somebody to cut a peice of cake! bahahahah set back the clocks in your house so everybody is screwed up! bahahahaha tell your parents you have a kid if your still a teen or something! bahahahahah take a bunch of stuff out of your house and say you got robbed! bahahahahah but I don't know what else!be creadtive!

well me and my bro pulled an awesome one last year! so we have a sink where there a hose thing and you turn the water on and it comes out the faucet but if you push and hold a button on the hose then the water only cums out that way. but if the waters not on is doesnt do anything. so my mom wakes up and puts water into a mug 4 coffee. she was so tired she didnt realize that we had put a rubber band on the hose so it would squirt at her! rofl lmao lol

we used to switch the sugar and salt.
