Jimmy Fallon Reveals the ‘Best Pranks Ever’

April Fool's Day has come and gone. But, as most professional jokesters will tell you, the best pranks are pulled during the 364 days a year that aren't specially designated for that behavior.

So while Jimmy Fallon's latest Late Night Hashtag -- #bestprankever -- was intended to celebrate April 1st, the tweets he received work as guidelines for pranks that you can pull on friends and family any time of the year.

Some of those pranks were just plain cruel. Like the doctor who opens up his patient's files and then says "yikes." There are some things you just shouldn't kid about!

But others were gold. If you know somebody who is hopelessly tech-challenged, a tweet from KRIST3NSPY shows you how you can make them the fool.

"I tell my dad that USB jump drives are voice activated so he says "Activate" everytime he plugs one in," the tweet read.

If you have a great prank you pulled on someone that you'd like to share, you can do so in the comment section. No 140 character limit here.
