• Warning: Spoilers
    In this episode everyone including their family, the dog, and school officials can't tell the twins apart. They claim that the twins are identical. The twins are not identical. I can tell them apart. All you have to do is look at the opening credits to know they don't look alike. In this particular episode Tracy lost a tooth but they claimed it was Trevor. Then in bed Tracy was in Trevor's bed and said Trevor owed him a quarter, but it was Tracy's quarter from the beginning because it was Tracy's tooth in the first place. If the writer wanted Trevor to lose the tooth, they should have had Jeff play the part of the twin who lost the tooth. It was Joel"Jason" who played the part of the twin who lost the tooth. Jeff Fithian plays Trevor and Joel"Jason"Fithian plays Tracy.
