For Fahim Saleh, prank calls are more than just a distant memory from his teenage years; they're his meal-ticket.
The 25-year-old started PrankDial.com while in high school but later revamped the site into a profitable small business, Mashable's Sarah Kessler reports. Saleh has also led efforts on other web projects and applications, but the classic sleepover prank continues to be popular among young teens.
The site allows users to send family and friends one of more than 100 pre-recordings, including the "I'm late" pregnancy scare and the infamous "Rickroll."
PrankDial.com was even recently featured on The Stir's suggestion list for April Fools' Day ideas, where blogger Linda Sharps admits trying a joke on her husband and "still laughing about it more than [a] week later."
Users can send up to three free calls per day, according to Mashable.
Of course, not everyone is a fan of the practical jokes.
Saleh has regularly received calls from police, who say certain residents are fed up with the prank calls.
"There's always going to be people abusing the site," Saleh told the London Free Press in 2010. "But we try to help out people who are being harassed and we put restraints on how many calls they can make and we encourage people who are being harassed to get on the no-call list."
According to his personal website, Saleh drew his inspiration from Google co-founders Sergey Brin and Larry Page were merely "two young entrepreneurs challenging the giants and succeeding."
But as a slew of bright teenage boys and girls have proved, age has nothing to do with one's level of success -- no matter what the field.
Just this week, 17-year-old physicist Taylor Wilson made headlines for his advances in nuclear safety. The teen scientist has even taught a graduate-level nuclear physics course at the University of Nevada-Reno.
And now Wilson's working on finding a cure for cancer -- that is, if Angela Zhang doesn't find it first.
The 17-year-old girl received a $100,000 check from a science contest earlier this year, and it's been said her research could lead to a potential cure for cancer.
