Matthew and Gregory were the original twin sons in Everybody Loves Raymond.
They are just like any other twin 2-year-olds. They like to play and cause trouble for the parents.
They were filmed as Ray and Debra's sons in the pilot episode. But after the creators of the show got the green light to continue on with an entire season, Matthew and Gregory were replaced with Michael and Geoffrey, played by Sullivan and Sawyer Sweeten.
