Hey give me a minute - gotta tell you something: 

Don't mess with Bill
Don't mess with Bill
(Don't mess with Bill) Say it one more time!
(Don't mess with Bill) 

Now I know he's a guy who put tears in my eyes
A thousand times or more
Oh but every time he would apologize
I loved him more than before 

Hear what I say, girls keep away, ah ah ah
Don't mess with Bill
(No no no no, Don't mess with Bill) Leave my Billy alone 

(Don't mess with Bill) Get a guy of your own
(Don't mess with Bill) 

Now there's Johnny, there's Joe and there's Frank and Jim
Just to name a few
Now, Bill's got me and I've got him
I'm sure there's one for you 

Hear what I say, girls keep away, ah ah ah
Don't mess with Bill
(No no no no, Don't mess with Bill) Cause he's mine all mine
(Don't mess with Bill) I say it one more time
(Don't mess with Bill) 

Though I tell myself he wants no one else
But keeps coming back to me
Now I'm in no position to want competition
I want to be sure as can be 

Hear what I say, girls keep away, ah ah ah
Don't mess with Bill
(No no no no, Don't mess with Bill) Leave my Billy alone
(Don't mess with Bill) Get a guy of your own
(Don't mess with Bill) Cause he's mine all mine
(Don't mess with Bill) I say it one more time
(Don't mess with Bill) Hey yeah yeah yeah
(Don't mess with Bill) Hey yeah yeah yeah
(Don't mess with Bill) Leave my man alone
(Don't mess with Bill) Get a guy of your own
