Parts 3 through 23 had Felix Cheng's disclaimer he used in KTTE 10-17. They were replaced with Klunk and Zilly making an intro. Although the Klunk and Zilly intro was removed from Parts 24, 25 and 26 for the reupload to SonicJrandSarah as a result some troll illegally downloaded the intro.
In Part 11, the letters were changed to be like they are in Thomas style. This was because the letters were not available on his computer between Parts 10 and 11.
Rolfcopter has appeared in ETTE 5 times due to Eli not knowing about his sock-puppets.

In "Stephanie, HarrisonMladenov and DoffieCat5 in ETTE merchandise", the title said "StephanieMladenov and DoffieCat5 in ETTE merchandise". This was because Stephanie and HarissionMladenov were both socks from Rolfcopter. StephanieMladenov was also a DA username Rolfcopter made which was a non-sock.
In ETTE 18, Kevin Highly was Rolfcopter's only apperence Eli knew was him at the time the video was made.
Parts 1-10 were remade for the reupload to SonicJrandSarah. Parts 3-10 no longer had the FC disclaimer in them, but since every other part remained as it was, parts 11-23 kept the disclaimers.
