With most items priced  well under $20, think of it as a wise guy’s gift guide on a budget. You’ll surely be the talk of the party, and your friends will enjoy hours and hours of fun and laughs as they use your creative, amusing gifts which will ‘keep on giving’.

1. Exploding Prank Pen

The Exploding Pen is an office prank classic. Don’t you just love it when a co-worker (who, incidentally never lets you borrow anything from her) asks to have one your pens? And then she forgets to return it. And then you have nothing to write passive aggressive office notes with. Take care of this issue by gifting her an Exploding Pen. It only costs $2 and explodes instantly, when someone takes the cap off.

2. Trashed Sticky Notes

Next on our list of funny prank gifts ideas come these Trashed Sticky Notes. Do yourself a favor and gift them to yourself. They’re just $6.75 and they will make sure all your co-workers buy their own gosh-darned office supplies. Never again will they ask to borrow ‘just one sticky note’, when they see how great these look. You will be the only one to know that, while they may look like they come from the bottom of the trash heap, they are actually brand new.

3. Disappearing Civil Liberties Mug

Do you have a friend that’s politically-minded? Gift them the Disappearing Civil Liberties Mug, microwave-oven safe and priced at a little under $11. Then invite yourself over for coffee the following morning and watch their dismayed face, as they realize that their beloved rights and liberties… are slowly drifting away. Sadly, much like in real life.

4. Work Trophies

When they see the Work Trophies you’re handing out, your co-workers will want to get in on your good graces. But there’s a reason why this item is on the prank gifts ideas list. They are actually the most sarcastic, shaming awards out there. If you plan to resign with a bang, award your annoying colleagues with such trophies as the brownnoser or slacker of the year. At least they’ll know where you stand.

5. Shocking Mouse

Do you suspect someone is using your computer at work while you’re out? Make sure they get what’s coming to them with the $5.9 Shocking Mouse. Lifelike, life-sized and very realistic, the mouse zaps the illicit user with a small electric charge, which will make them think twice about using a PC they do not normally have access to.

6. Sarcastic 8-Ball

Everyone loves 8-Balls, don’t they? Not really. Those of us who are not as naïve as to believe in the random ‘predictions’ of a plastic ball love the Sarcastic Ball more. It costs only $7 dollars, it looks just like the original, but it provides actually intelligent replies, such as ‘Ask me if I care,’ and ‘Yeah, right!’ It features twenty answers and will surely make you popular with your clients, colleagues and boss. Depends on their sense of humor, really.

7. Unfortunate Fortune Cookies

Chinese takeout is a staple of office cuisine and people just seem to adore fortune cookies. They feature cute, positive, uplifting messages about the future. Well, these Unfortunate Fortune Cookies replace your run-of-the-mill “Something good is in store for you” with much more interesting revelations. Such as “You just ate cat”. The kit includes ten cookies and ten witty fortunes and costs $9.

8. Birthday Beer

It’s Steve’s birthday, he’s finally 2 and can legally drink! Celebrate with custom-made beer bottles, which feature the portrait of old Stever himself. You can further personalize the bottle by replacing the usual brand slogan with your own wording and replacing the expiry date with the birthday boy/girls’ birth date. Each label costs $24.95, but will totally make you the talk of the party.

9. Two-Carat Bling Mug

You know your friend Jane, who’s down in the dumps because everyone at the office is getting married and flaunting their expensive engagement rings? Cheer her up by offering her the Two-Carat Bling Mug. One of the best prank gifts ideas yet, this graceful porcelain mug will make Jane the talk of the office and put a smile back on her face.

10. Backwards Clock

Imagine the confused looks on your coworkers’ faces when you first put up the Backwards Clock on your desk. It still ticks forward, but the numbers are on the ‘wrong way’. If they ask, just tell them you’ve found a simpler way to count down the minutes left until you get to go home.
