Crazy Frog

The Crazy Frog was spawned in 17-year-old Swede Daniel Malmedahl's bedroom in 1997 as an impression of the sounds made by his friends' souped-up two-stroke scooters as they raced around local streets. His efforts were posted up on the Internet, at which point he was invited to perform live on national TV. Several websites then picked up on the phenomenon, with fellow Swede Erik Wernquist setting it to the now-famous amphibian animations. The pair were then approached by the real player in all of this, ringtone company Jamster, who swept Crazy Frog to prominence worldwide, shifting $15 million's worth of tones in the U.K. alone and propelling it into the charts to the strains of Harold Faltermeyer's "Axel F."
