He can be seen at Citi Field during Mets home games, has appeared in several commercials as part of ESPN's This is SportsCenter campaign, and has been elected into the Mascot Hall of Fame.

[3] When the Mets moved to Shea Stadium in 1964, fans were introduced to a live costumed version, portrayed by team ticket office employee, Daniel J. Reilly.

Mr. Met is believed to have been the first mascot in Major League Baseball to exist in live-action (as opposed to artistically rendered) form.

He was phased out prior to the upsurge in mascot popularity caused by The Famous Chicken and the Phillie Phanatic in the late '70s.

He is usually found near Mr. Met's Kiddie Field where fans can meet and pose for pictures with him.

[11] In 2015, a far more detailed Mr. Met backstory was written by a longtime fan in cooperation with the team and published by Mascot Books.

In 2007, Reilly wrote a book about his experiences with the team, called The Original Mr. Met Remembers.

Mr. Met was portrayed from 1994 through 1997 by AJ Mass, currently a fantasy sports writer for ESPN.

[16] In a 2003 This is SportsCenter ad, when the show ends, everyone rushes out of the studio, creating a massive traffic jam.

[17] When Josh Hamilton shows up to use the microwave, Mr. Met angrily gestures at him and walks away.

He was also featured in commercials for MLB 06: The Show, a video game for Sony's PlayStation 2, where a camera crew followed him around as he performed his daily duties, such as buying coffee and picking up his laundry.

His estranged father (Garry Marshall) is with him and the senior Madison gets Oscar so mad that he hits Mr. Met in the head.

Mr. Met and the Phillie Phanatic did a MasterCard commercial in 2013 to raise money for ending cancer.

[20] According to his 2019 Topps Opening Day Baseball Card, the "hustling humanoid [still] loves getting selfies taken with fans and raising money for charitable causes."
