Chuck Lorre is a writer, creator, and producer with the magic touch when it comes to comedy on television, with shows like Two and a Half Men, The Big Bang Theory, The United States of Al, and Young Sheldon to his name, among many others.
He selected a special card to honor Young Sheldon hitting 100, and then used a card at the end of United States of Al to poke fun at it.
If you want to revisit earlier days of Young Sheldon, you can do so with a Paramount+ subscription.
The vanity card tradition for Chuck Lorre shows began back with Dharma and Gregg, which ran from 1997 – 2002 and featured Thomas Gibson in a pre-Criminal Minds comedic role.
