His wife Margo, in a 1980 People magazine profile of the imposter, said Bremen was "fulfilling a grand fantasy to be in the limelight.

[7] On February 4, 1979, Bremen donned a Kansas City Kings uniform and got onto the floor during pre-game warmups for the NBA All-Star Game at the Pontiac Silverdome.

[8] (He was outed by genuine All-Star Otis Birdsong, who really did play for Kansas City: "You're on my team, and I don't even know who you is.")

On July 17, 1979, with the help of telecaster Dick Schaap and Kansas City Royals third basemen George Brett, Bremen snuck onto the field dressed in a New York Yankees uniform at the Major League Baseball All-Star Game, held at the Seattle Kingdome.

Bremen shagged flies in the outfield for a half-hour and attempted to pose for a group picture with future Hall of Famers Brett, Reggie Jackson, Joe Morgan, Mike Schmidt, Gaylord Perry, Dave Winfield, Steve Carlton, Nolan Ryan, Carl Yastrzemski, Lou Brock, and Tommy Lasorda.

[6] In 1986, wearing a New York Mets uniform, Bremen again shagged flies in the outfield during the All-Star pre-game at the Houston Astrodome, when he was discovered and berated by NL All Star coach, then LA Dodgers manager Tommy Lasorda.

In preparation, Bremen lost 23 pounds (10 kg), practiced drag routines with his wife, had a replica Dallas Cowboys cheerleader uniform custom-made, shaved his legs and spent $1,200 of his own money.

During the game, Bremen burst onto the sidelines in boots, hot pants, falsies and a blond wig.

[5] In 1981, Bremen posed as a line judge referee at Super Bowl XV at the Louisiana Superdome in New Orleans.

[10] In 1982, Bremen, dressed as the San Diego Chicken, was stopped from entering Super Bowl XVI at the Pontiac Silverdome.

[4] At the 1979 U.S. Open, Bremen (who had a 7 handicap)[3] sneaked on to Inverness Club in Toledo, Ohio, and played a practice round with Wayne Levi and Jerry Pate.

Bremen, wearing a disguise and claiming to be a qualifier named Mark Diamond, went in search of Couples, who was playing a practice round with Haas.

Couples remembers: He comes out of the shrubs on the second hole and hits this tee shot that buzzes the spectators....

[1] Due to his Great Imposter successes, Bremen became a celebrity in his own right in the '80's and made a number of TV appearances, including The Tonight Show with Johnny Carson, Late Night with David Letterman, and was named Sportsman of the Week, twice, by Dick Schaap on The Today Show.

In 2022, Bremen and his antics were again the focus of an ESPN documentary by E:60, with the added bonus of his background as a sperm donor during the 1970s and 1980s.
