If you’re just dying to do a prank on someone, you probably should steer clear of this one. It’s about as bad as the can of nuts that spews fake worms at people. Although, at least that one’s classic, this one’s just bad. You place the tongue in your mouth and then inflate it. It will inflate up to 3 times its original size. For obvious reasons, this shouldn’t be given to small children, that whole choking thing is a slight issue for them. Luckily, this prank is cheap, you can pick it up for $3.99 on Amazon.
