Could've been so easy

Could've been a friendly phase

Could've been simple

Could have it, should have

But that's not the case

Tell me who are you

To be calling me names

You're making yourself the fool

Ain't that a shame.

You can call me a

liar, cheater, loser

Takes one to know one

You can say I'm bitter,

call me, a quitter

Takes one to know one

Takes one to know one

And I know you.

Now you're pointing fingers and

The point is lost on me

Do you hate to see me happy?

Does it fill you with jealousy?

What'cha trying to prove

By putting me down?

Sorry, the joke's on you

Like tears of a clown.

You can call me a

liar, cheater, loser

Takes one to know one

You can say I'm bitter,

call me, a quitter

Takes one to know one

Takes one to know one

Yeah, takes one to know one

And I know you.

I know you

Yeah, yeah, yeah, ohh.

You can call me a

liar, cheater, loser

Takes one to know one

You can say I'm bitter,

call me, a quitter

Takes one to know one

Takes one to know one

Takes one to know one

Takes one to know one

You can say I'm bitter,

call me, a quitter

Takes one to know one

Takes one to know one

Yeah, takes one to know one

And I know you.
