From Homestar Runner Wiki
Occasionally in the Homestar Runner body of work, characters will start one word or phrase before they've finished the one before it, creating an overlap in their voice. This most often occurs in Strong Bad's email songs.
- In Search of the Yello Dello New Version — Homestar overlaps himself while singing "Hello Yello Dello Dello" on the mountain top.
- Email techno — Each new addition Strong Bad makes to the song he creates overlaps the rest of the song.
- Email different town — The second line of Strong Bad's email song is two overlapping clips of the same line, "check your email and check your email".
- Email long pants — The second line of the email song starts just a second before the line before it stops.
- Email pop-up — In the email song, "I was born to check email and eat lots of cake", there is a very slight overlap of the words "email" and "and".
