On Chef Aid, the song opens with a mock phone call between Sid Greenfield (voiced by Trey Parker) and South Park creators, Matt Stone and Trey Parker, talking about putting the song on the album. In the mock phone call (which begins on the previous track, and continues throughout "Horny") Matt and Trey repeatedly voice their dislike for the song, and Sid Greenfield finally agrees not to include it. (Of course this is after the song has already finished playing in its entirety.)
Hot 'n' Juicy were initially a duo of singers, Emma Southam and Nadine Richardson. They appeared on the 1998 version of "Horny" and the 2006 mash up "Horny as a Dandy". They were residents of a tower block on the former Lee Bank estate in Birmingham.
They became a trio later in 1998 when they were joined by Nikki Belle, but were again reduced to a duo in 1999 when Richardson quit the band.
