Unknown artist

Hi-
I'm trying to remember the artist that sang this rap song in the 80's. I think the song is named "split personality" but i can't find it. it kinda goes like this:
split personality, split personality, i can't control my split personality (chorus)
i'm a singer, a dancer, a rapper too
i can do anything that anybody can do
i can act like a crook and steal a book off a shelf
then i can act like a cop and arrest myself.
to do that you gotta have a strong mentality, in other words, gotta have a split personality
as a matter of fact, to be exact, come to think about it, i'm somewhat like that.
you see my split personality goes and comes, like two people trapped inslde of one.
one's a nice person, the other is not. one drinks cold water and the other drinks hot.
one minute your in my arms and i'm feeling you around then before you know it baby i'm beating you down, then i'll say sorry and together we'll cry, then i'll look you in the face and spit in your eye.
i'll snatch a baby's lollipop and then give it back, smile at the mother before i get slapped.
help an old lady across the street, then i'll trip the ? by sticking out my feet and then i'll help her up before she dirties her dress and give her 5 dollars for all that mess

i think i got the order of the verses mixed up a little but can anyone help with the title and artist

Thanks.
