Sadie, known as Super Sadie to most people, is a two year old little girl who is suffering from Fibrolamellar Hepatocellular Carcinoma, which is a type of liver cancer. Sadie loves dancing, music, drawing, watching pro wrestling on TV, and going to live wrestling events. She appeared on one of Angry Grandpa's videos when her family were visiting Charleston, and they wanted Grandpa to visit her and take her to Frankie's Fun Park for Miniature Golf. The two families spent the entire day with her to make her have the best day of her life. At the end of the video, Grandpa is nearly in tears knowing she would remember that day forever. She currently needs 3 rounds of chemotherapy, and has completed 1 on May 19, 2013.
- Sadie has her own GoFundMe page for her chemotherapy here 
- Sadie has also been noticed in other news medias other than Grandpa's Channel.
- After the video was posted, Michael moved into a new home, causing critics of the Angry Grandpa Show to believe that he took some of Sadie's funds for himself. He commented that stealing from a child in need was a monstrous thing to do, and said that him and Grandpa were simply advertising their page since it is controlled by Sadie's family. Some fans to this day still don't believe him, as three thousand dollars were 'donated' from Sadie's GoFundMe page.
