Got Any Good April Fools Jokes?

I am one of those people who has spent my whole life playing jokes on people. I normally start preparing to play a good trick on all my friends and family members weeks before April Fools Day.

I'm either too old or too tired because I haven't come up with one single thing. My brain is like mush right now. I know everyone is waiting...but I've got NOTHING! Help...anybody have any ideas? I can't go the whole day without one single trick!
