|Did you mean Jonnie, a main character from Grand Theft Auto Advance?|
Oily Johnnie is a character in the Grand Theft Auto series whose name can be seen on a store sign in Grand Theft Auto III and Grand Theft Auto: Liberty City Stories. Oily Johnnie runs Oily Johnnie's Massage Parlor in the Red Light District of Portland Island, Liberty City. Oily Johnnie should not be mistaken for Jonnie, a main character in the game Grand Theft Auto Advance.
The name 'Oily Johnnie' could be another crude sexual joke, as the name is referring to a penis with lube on it.
