“This is Oliver "Ladykiller" Biscuit on Fever 105. 105 degrees, ooh, I'm just gettin my groove back on. Mmm... Susan just called from Prawn Island saying she's having a party and "can I recommend something to get people in the mood?" Well baby, I can recommend myself, I'm cool as a cucumber and just as useful... Oh yeah... Mmm...”
— Oliver "Ladykiller" Biscuit at the start of the song "Last Night a D.J. Saved My Life" in GTA Vice City
His appearance and voice is heavily based on legendary soul singer Barry White. His name could be one of several puns such as "I'll have your biscuit", as he's large in size and frequently discusses the food he eats on the show.
