If you want to see the Easter Egg for yourself, you’ll need to rip a CD to your Xbox’s hardware. When your console prompts you to name the album, type, “Timmyyyyyyyyyyyyyyyyyyyyyyyyyy!” That’s Timmy with 26 ys (we’re starting to see why no one discovered this Easter Egg on their own). As Kotaku points out, there’s no need to count the letters. Instead, fill the entire field and then replace the last letter with an exclamation mark.
Now prepare for a history lesson in what it was like to use technology in the mid-aughts as your Xbox slowly copies the music files over to its mechanical drive. Once it’s done, open the settings menu and navigate to the “System Info” option. The console will now treat you to a new credits screen listing the members of the Xbox Dashboard team.
