When Dexter creates a new invention to get DeeDee's rudeness under control, her foolish antics cause both her and Dexter to end up in the machine, resulting in them becoming polite, and their rude, evil counterparts being made. Now, the polite Dexter and DeeDee must find a way to rid of the disrespectful clones of themselves before they cause even more trouble.—j-jessie-weaver
In this unaired Dexter's Laboratory segment, Dexter builds a brand new invention that splits people into two copies: one rude and one polite. When Dexter demonstrates his invention to Dee-Dee, they get into a fight, and get trapped in the cloner. Their rude, potty-mouthed clones/egos then cause trouble and reckoning, and it's up to the polite clones to stop them.—Alex Lindell
Dexter feels that DeeDee's rudeness is becoming a restriction, so he decides to use a device on her than renders her polite and charming, however, the device goes awry, and it separates Dee-Dee into a good polite half and a bad rude half. The rude half swears and does other bad things and Dexter must fix DeeDee before the rude half does something really bad.—Anonymous
