The clue was "Easy," a romanization of the combination of their surnames 이 (Lee/Ea) and 지 (Ji/Sy). Whenever they are paired up, they are also known for performing their "Feel, Touch, Cross!" cheer before each mission.
Gaisy (개이지)	Ji Suk-jin, Lee Kwang-su, Gary	This is a portmanteau of "Gary" and "Easy" given in episode 72 after they were not chosen by the guests of the episode. Thus combining all three of their names together by first syllable of their names 개 (Gae/Ga), 이 (Ee/i), 지(Ji/sy).
Lee-Yu-Ji (이유지)	Yu Jae-suk, Ji Suk-jin, Lee Kwang-su	An evolved form of the Easy Brothers, it was created as Ji Suk-jin was getting jealous of Lee Kwang-su being close with Yu Jae-suk, and calling themselves Lee-Yu in episode 81. Asking whether Lee Kwang-su was withEasy or the new Lee-Yu, Yu Jae-suk replies "that is the reason" ("the reason" is "Lee-Yu-Ji" in hangul), and Ji Suk-jin reluctantly joins them to become Lee-Yu-Ji, which is their last names put together.

Kook-Su (국수) Tiger and Giraffe (호랑이와 기린)	Kim Jong-kook, Lee Kwang-su	This was formed in Episode 82 where Lee Kwang-su and Kim Jong-kook were paired into a team. So their names were combined to form "Kooksu" which is a pun because it also means "Noodles" in Korean. Also, since Kim Jong-kook resembles a tiger and Lee Kwang-su resembles a giraffe, their relationship is also known as Tiger and Giraffe. This happened again in Episode 84 where Lee Kwang-su and Kim Jong-kook were chosed by the opposing team to pair up together with paper handcuffs, leaving both of them stuck to each other for the rest of the episode.
Kookisy (국이지)	Ji Suk-jin, Lee Kwang-su, Kim Jong-kook	This is a portmanteau of [Kim Jong]-"kook" and "Easy" given in episode 83 after they formed a team. Thus combining all three of their names together by first syllable of their names 국 (kook), 이 (Ee/i), 지(Ji/sy).
