Sports Commentators (later renamed Sportscasters) was played on both the British and American versions of Whose Line.
The only time the rules are edited is when Rory Bremner plays, as a sportscaster. He is given the role of someone to impersonate during the game. When the game came to the United States, Drew Carey became one of the commentators in later playings.
Despite the suggested activity being very mundane, the actions of the event performed by Ryan & Colin are very violent. And like any sports broadcast, replays are often used, complete with a rewinding tape and freeze-frame.
Whenever Greg Proops was featured one of the sportscasters, he would invariably use a line amounting to "It doesn't matter/I don't care (details ranging from where someone's from to how long someone has done something or similar), that's gotta hurt!" Greg Proops would use this type of line as one of the two heads of Fode and Beed, an alien sportscaster covering the podrace in Star Wars Episode I: The Phantom Menace. That line, for reference, went like this: "I don't care which universe you come from---that's gotta hurt!"
