Role in Angelica Breaks a Leg
In Angelica Breaks a Leg, Antonio was sent to the hospital around the same time as Angelica, who had tricked Stu and Didi into thinking she broke her leg to get attention from them. While Antonio did have a broken leg, Angelica's leg was fine, but because the young Dr. Hoagie Dooser had trouble keeping track of both Antonio's surname and Angelica's, he had mixed up their X-rays. Thus, he had believed that Angelica's leg was truly broken and Antonio's wasn't, and recommended keeping Angelica's leg in a cast, despite Didi's insistence that she and Stu find a second opinion from an older, more experienced doctor. Towards the end of the episode, Antonio can be seen in a hospital bed with Angelica's file at its foot, revealing that he injured his broken leg even more when he played in a football game. After Dr. Dooser explained to Stu and Didi that he had mixed up Angelica and Antonio's X-rays, he apologized to him for the mix-up.
