Bongo Jam
Bongo Jam is a recurring gag that first appeared in Episode 7.2.
It originated in a clip from Big Brother: Celebrity Hijack, where housemate Calista was shown recording a refrain from the song "Bongo Jam" by Crazy Cousinz, which consisted of the lyric "I love to play my bongos in the morning". She also referenced the song "shaking up the funky house scene".
Whenever bongos were mentioned between Series 7-9, Harry would pull some out, sing the line, and reference the song's effect on the funky house scene.
