Lost Regular Show YTP

I been looking for a Regular Show YTP I saw when I was 9 called "Ytp:Regular Show But I have a damn decipt bitch!" it was a YTP of the episode where Mordecai and Rigby try to get a refund for a roleplaying board game they didn't like. the only clip from it I remember is where SpongeBob pops up to say "imagination" at the same time as the game shop employee. I already tried the Wayback Machine but couldn't fine the video.
