Did you know the Crazy Frog sound was made by a 17-year-old boy in Sweden who was just trying to imitate the sound of a two-stroke engine with his mouth? His name was Daniel Malmedahl. He recorded it in 1997 as a joke, uploaded it to the internet, and forgot about it. Six years later, a Swedish animator stumbled across the file, spent eight weeks building a character around it, and posted it online. He had no idea who made the sound. The credits just said anonymous. A ringtone company found it, renamed the character Crazy Frog, and made over 400 million dollars. Daniel was 24 and working as a computer components salesman when it peaked.
