The secret inside me was trapped beyond a doubt but now my most terrible secrets out!
— The Study Group
Sometime in their fourth year at Greendale, a general sense of malaise falls over the study group. Feeling stuck in a rut, they decide that they all need to do something exciting away from Greendale. The group goes on a hot air balloon ride hoping to ease their ennui but take off without their balloon guide. They land in the forest and after encountering a mountain man who gives them psychotropic truth telling berries, they set up camp. As they come down from the drugs they ingested, they reveal to each other their darkest secrets by singing the song "My Most Terrible Secret". The song is first heard in the Season Four episode "Intro to Felt Surrogacy".
Adam Levine, lead singer and song writer of the band "Maroon 5", helped co-write this song. He was roommates at one time with the episode writer Gene Hong. He also provided the melody which was taken from an unreleased song from Adam's previous band "Kara's Flowers" titled "Angel in Blue Jeans"
