10 pranks to pull on your friends... Assuming they will still want to be your friend after these humorous gags. Disclaimer: not responsible for friendships lost over these pranks. Have fun responsibly.

1. Air Horn Alarm

With a bit of duct tape and an air horn, you can snicker in anticipation of that loud noise. Whether you want to put it under a chair or behind a door, you can be sure to get a reaction.

2. Wrap It Up

A personal favorite of mine. Saran wrap is a joker's dream. You can cover someone's vehicle, stick it in a doorway for people to crash into, or the unthinkable, cover the toilet seat with it! Let's just hope they're forgiving!

3. The Imaginary Friend

If your bestie is obsessed with someone else, teach them a lesson by making them disappear. Get everyone involved in pretending a well- known person never existed. The best way to make it believable is to get rid of any personal belongings, contact info, or pictures. If you get it right, he might start thinking he had dreamed the person up!

4. Ping Pong Gone Wrong

A true classic. Simply fill an enclosed area with ping-pong balls till' there is no room left, then wait for the disaster to unfold. The best part is, your friend won't have any idea what to do with all the ping-pong balls. Unless they are a professional at ping-pong.

5. Creepy- Crawly

What is more amusing than watching a person shriek at the sight of a bug? Or a spider? Or a snake? No matter what your dear friend is afraid of, I'm sure they'd be shaking in their boots when they find one of these creepy- crawlies in their desk, or a box, or even a backpack.

6. That's Not Shampoo

Depending on the patience of your friend and how much you value your life, this prank may have drawn a line. But how fun would it be to "accidentally" switch your friend's shampoo with hair dye? I'm sure a nice pink tone would frame their face nicely...

7. The Good Ol' Smack Cam

Just a little bit of whip cream goes along way. For those of you who don't know, the smack cam is like pie in the face, only a whip-creamed slap while videotaping. Whether you leave your victim speechless or end up being chased in hot pursuit, the audience will be thoroughly entertained.

8. The Auto-Correct Monster

No one likes an unfortunate auto-correct. But did you know you can change words in your friend's phone? Laugh at their misfortunes as "hey" becomes "penguin waddle" or "no" becomes "Iron Man wears ladies' underpants". Extra points for including a group text.

9. The Febreeze Grenade

Like the Axe Grenade, the Febreeze grenade offers an overwhelming scent which is sure to leave your friend confused and afraid at it's sudden presence. However, you get to be immensely amused... unless you are in the same room...

10. Friend For Sale

If your gullible friend gave you their private number, why not test their friendship in the best way possible? Put up an add on Craigslist with an absurd title and post their private number. As calls come flooding in, asking for a chimpanzee maid, you'll be able to look on with a feigned confusion.
