The hosts of the show were the owarai duo Ninety-Nine (Takashi Okamura and Hiroyuki Yabe).
On July 19, 2006, during Ibaraki Golden Golds exhibition road trip to Hokkaidō, Keiichi Yamamoto of Gokuraku Tombo was charged with sexual assault on a 17-year-old girl.
Yamamoto ultimately forced to leave the show and the showbiz, as He was dismissed from Yoshimoto Kōgyō in that same day.
The winners and new regular members were Jaru-jaru (Shusuke Fukutoku, Junpei Goto), Tanpopo (Emiko Kawamura, Kumiko Shiratori), Atsushi, Satomi Shigemori, and Motokatsu Sannaka.
In 2010, Takashi Okamura of Ninety-Nine left the show for a few months in order to recover from an unspecified illness.
Each member plays as a different character showing typical Rock and Roll and Rockabilly stereotypes.
This whole process must follow the rhythm of a chant (mostly consisting of repetitions of bun-bun ("vroom", the sounds of a motorcycle revving) which gets faster as the game progresses.
Any player who fails to give the correct counter is put up against one or more aggressive sumo rikishi who then humiliate them.
With repeat failure players often have a "secret seal" smacked onto their skin which has some sort of embarrassing image on it, and is always censored on screen.
The losing player is then subjected to a punishment by being hoisted into a full train car of big sized men for around half a minute.
Cocorico's Endo Shozo and Tanaka Naoki, EXILE, Funasshi, Murakami Shoji, Jimmy Onishi, Sanma Akashiya, Atsushi Tamura, and model Lola have participated as guests of the Mechagginton corner.
Only available for download on Japan's Apple's Appstore or Android's Google Play store, the Mechagginton app features a rhythm game where the player must match the correct onomatopoeia to the object displayed in the center of the screen.
This corner parodies the opening sequence of the period drama, Ooku - Hana no Ran.
If even one member of the team guesses wrong they are given a result of "Maicching" (probably a pun using mai, 昧, meaning "vague" and ching from "matching") and the floor opens dropping them into the ice cold water below.
The following are some of the names of some of the international characters each member plays: Parody of the Japanese version of Who Wants to Be a Millionaire?.
At the end of the exam, the "teacher" and his assistant (Takashi Okamura and Fuji TV announcer Mizuki Sano) grade the papers and go about ridiculing the incorrect answers.
After this, the test rankings are announced starting from the top and lowest-scoring person is eventually named and crowned in a special mock ceremony.
Occasionally, some of Mechaike's own members are themselves duped into playing, mainly for comic effect and to round out the bottom of the test rankings.
Yasuko Mitsura portrays herself as a high-scoring, overachieving teacher's pet while, Koji Kato is considered a math wiz of the group, once scoring 100 on the mathematics portion of the exam.
His performance during the tests solidify his natural airheadedness compared to his role of the tsukkomi in Yoiko.
In 2013, an exam episode featuring 15 AKB48 members was filmed with the 7 lowest-scoring girls forming the AKB48 sub-unit "Baka 7" (Idiot 7); a play on words of "Kami 7".
