Lyrics:

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
Liar, cheater, loser
Takes one to know one
(Takes one to know one)
You can say I'm bitter,
Call me, quitter
Takes one to know one
(Takes one to know one)
Yeah, 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
Liar, cheater, loser
Takes one to know one
(Takes one to know one)
You can say I'm bitter,
Call me, quitter
Takes one to know one
(Takes one to know one)
Yeah, takes one to know one
Yeah, takes one to know one
And I know you

I know you
Yeah

You can call me
Liar, cheater, loser
Takes one to know one
(Takes one to know one)
You can say I'm bitter,
Call me, quitter
Takes one to know one
(Takes one to know one)
You can call me
Liar (liar), cheater (cheater), loser (loser)
Takes one to know one
(Takes one to know one)
You can say I'm bitter (bitter),
Call me (call me), quitter (quitter)
Takes one to know one
(Takes one to know one)
Yeah, takes one to know one
Yeah, takes one to know one
And I know you

Could've been so easy
Could've been a friendly phase
