From Homestar Runner Wiki
The Geddup Noise was the chair-on-wood sound
Strong Bad made when he got up from his computer and sat back down, even though the stool was scraping against carpet. Strong Bad originally called it "the get up noise" in the email
the bet. It inspired
DJ Teh Cheat to create a Geddup Noise indie-tronic remix, which
Pom Pom used as a ring tone for his
cell phone in
technology. According to Strong Bad, The Geddup Noise eventually bought a house in the Coches and now just snowboards all day, still occasionally popping up in very odd celebrity endorsements. In the email
geddup noise, it was established that Chairscoot replaced The Geddup Noise somewhere around email #84 (
kids' book) and now provides the sound effect for Strong Bad leaving his computer.
