For some people, April Fools' Day is a day to say, "whoopie" -- as in cushion.
Celebrated since medieval times, the humorous holiday is perfect for those people who want to get a rise out of friends, family -- or even authoritarian figures who have tortured them the other 364 days of the year.
"It's an excuse to vent frustrations, and be playful and harmless," according to prank artist Joey Skaggs, whose specializes in fooling the media into printing outrageous stories.
One year, Skaggs convinced major New York newspapers that he'd created a "cathouse for dogs," where pooches could get sexually gratified by a "savory" assortment of "hot bitches"; another time, he was a guest on Good Morning America, where he posed as the leader of a group of ex military commandos who were now helping dieters as the "Fat Squad," a team that would physically restrain fat people, to keep them from breaking their diets.
But while pranksters like Skaggs spend months planning a stunt, most of us prank by impulse.
For those budding jokesters, there are novelty products like joy buzzers, fake ice cubes with bugs, and fart bombs to help them tease, annoy or fool their friends.
HuffPost Weird News has collected some of the classic prank novelties, as well as some new ones, to give you some ideas of what -- or what not -- to do on April 1.
We hold no responsibility for the consequences you may suffer for your attempts at humor (especially the fart bombs) but James Murray, one of the stars of the TruTV series "Impractical Jokers," believes you're less likely to get in trouble for any pranks you pull on April 1.
"Really, it's the perfect day to do a prank because you don't have to apologize to anyone," Murray told HuffPost. "I wish we could do every episode on that day."
Whatever prank you decide to do, be it an "I'm A Douche" coffee mug, a squirting ring or a nail through your head, Skaggs has some important advice: "All pranksters have to suspend any empathy, even momentarily, for the person being pranked."
