From World Series winners to tennis stars, David Letterman has had his fair share of sports figures on as guests in his 33 years on television. Here's a look at 10 notable sports figures to appear on either "Late Night with David Letterman" or the "Late Show with David Letterman."
David Letterman poked fun at the former Kansas City Royals shortstop with a device comparing his hits total to Pete Rose's 4,204 during an episode of NBC's Late Night with David Letterman on Nov. 6, 1985. Biancalana accumulated just 113 hits in his six MLB seasons but gained fame after hitting .278 in the 1985 World Series, helping the Royals beat the St. Louis Cardinals.
Biancalana showed he has a good sense of humor, too, when he brought Letterman one of his bats. "Actually this is a bat I used probably half the season," he said. "As you can tell, there are no ball marks on it."
WILLIAM "REFRIGERATOR" PERRY
After becoming the heaviest player to score an NFL touchdown, the former Chicago Bears defensive tackle appeared on Late Night on Nov. 11, 1985 amid the team's 15-1 Super Bowl season.
Perry told Letterman the heaviest he ever weighed was between 365 and 370 pounds in his freshman year at Clemson, but he said he's most comfortable around 300 pounds. Perry got a big laugh from the audience when he told Letterman he eats only one meal a day.
At the end of the segment, Letterman brought Perry into the green room to meet another guest, Jerry Seinfeld, to compare their size.
The former Chicago Bears quarterback appeared on Late Night on Tuesday, Jan. 14, 1986, before the Bears beat the New England Patriots in Super Bowl XX on Jan. 26. Letterman gave McMahon a headband that reads Late Night, and suggested that McMahon wear it under his helmet during the Super Bowl.
Marge Schott, then the Cincinnati Reds owner, appeared with her dog, Schottzie, on Late Night on May 13, 1986. Schottzie sported a Reds hat throughout the segment.
"I don't know what were doing up here," Schott said in an interview before the show. "They've been calling, and of course, I had to come up to New York anyway. I think it's really the dog they want."
David Letterman got out from behind his desk in a segment with Andre Agassi on an episode of CBS' Late Show with David Letterman on Sept. 12, 1994. Following an interview with Agassi, who won the U.S. Open that year after entering the tournament unseeded, Letterman attempted to return serves from the eight-time Grand Slam winner.
Letterman has long had an affinity for having his athletes play their respective sports on his show. In the April 14, 2008 episode of the Late Show, Letterman pitched to Wright, who donned his No. 5 jersey over a button-down shirt, from behind an L-screen in the middle of 53rd Street.
Have we mentioned that Letterman likes to play tennis? On his April 21, 2008 episode of the Late Show, Letterman had Maria Sharapova, a five-time Grand Slam winner, on as a guest and took her out to the streets for a game of tennis. This time, he brought comedian Billy Crystal in as a doubles partner.
Before her 2014 U.S. Open victory, Williams was a guest on the "Late Show." Once again, Letterman took on a tennis star outside of the Ed Sullivan Theater on a makeshift court.
