Summertime Loving, Loving in the Summer (Time)

Summertime Loving, Loving in the Summer (Time) is a song by Solid Bold that Rigby says he loves (or at least used to). It is introduced in This is My Jam. When the duo find a cassette tape of it while cleaning the gutters, Rigby tells Mordecai "this is my jam!" Mordecai dislikes the song, though, but agrees that he only liked it "that one summer in junior high." Rigby bugs Mordecai to listen to the tape, and Mordecai agrees, but says the only reason is because he wanted to take a break anyway. They listen to the song, and get sick of it quickly. Unfortunately, however, the song gets stuck in Rigby's head, and some quite irregular events follow.
