They are the longest-existing team in the D-League. Despite being in the D-League since the beginning, they have yet to win the TMNXT Tag Team titles. They've currently had two TMNXT Tag Titles matches but were unable to win either of them.
The Man In The Yellow Hat and Curious George first teamed up on episode 5 on the D-League, when they were part of the TMNXT Tag Team Gauntlet to crown new TMNXT Tag Team Champions. They were drawn 4th and defeated Johnny Bravo and Joey Ryan before facing The McNuggets for the belts. However, they were pipped to the post by the Trevolution representatives.
The duo was temporarily broken up due to Curious George being fired for attacking backstage staff. They were reunited when Season 2 began. They competed in the second TMNXT Tag Title Gauntlet on the 4th episode of Season 2 representing the The Orange Iguanas. They defeated "Murder" Ray Lewis and Mr Rogers before losing to the BK Value Meal. They teamed up in another tag gauntlet on Episode 10 and were the final participants against Lewis and Rogers. They were able to beat them again to earn a tag title shot on Episode 11. However, they were unable to defeat the Johnnywood Blondes.
- The team are the only team to still be teaming together since the start of the D-League.
