Carl Wheezer is the anxious, asthma-prone best friend from Nickelodeon's Jimmy Neutron: Boy Genius film and its 2002 television series, voiced by Rob Paulsen. His nasally delivery made him a lasting meme favorite long after the show ended. The doorbell edit, which reworks his voice into a household chime, circulates on meme soundboards and short-form video platforms where creators use recognizable cartoon voices for comic effect. It endures because the contrast between a mundane alert and such a distinctive character voice stays instantly funny.
