Oh now you didn’t!
This may be one of the better gags, because, while almost all of the switcheroos on this list are involving the twins working in tandem with each other, this is one twin actually deceiving the other twin. The question I have is, did the other twin also show up to take his class picture, and if he did, which one of the twin’s photos were used in the school yearbook? I think it would be hilarious if the twin who showed up and pretending to be his brother actually had his photo printed in the yearbook. That would be a story they could tell at partied for years to come!
