Jay works at an unnamed radio station.
He is only heard through Luna's radio in "Undie Pressure". He's giving away tickets for a Mick Swagger concert to the caller with the best British accent. Luna calls to the radio station and speaks in her British accent, losing the bet in the process.
He returns in "Making the Grade", to announce free passes for the Royal Woods Spa to anybody who can name the three classifications of rocks. Eager to win them, Lola quickly dials the number, and tells Lisa to give the answer. However, instead of naming the three classifications of rocks, she instead gives off three types of rock music, which costs them their chance of winning the tickets.
