you're so bad, you're so bad, you're so
you're so bad, you're so bad, you're so

you think you're in love
like it's a real sure thing
but every time you fall
you get yo' ass in a sling
you used to be strong
but now it's "ooh baby please"
'cause falling in love is so hard on the knees

you're so bad, you're so bad, you're so
you're so bad, you're so bad, you're so

we was making love
when you told me that you loved me
i thought ol' cupid
he was taking aim
i was believer when you told me
that you loved me
and then you called me
someone elses name

there ain't gonna be no more
beggin' you please
you know what i want
and it ain't one of these
you're bad to the bone
and your girlfriend agreed
that falling in love is so hard on the knees

you're so bad, you're so bad, you're so
you're so bad, you're so

chip off the old block

blowing a transistor
i feel like i have been hit by a fuck

you say that we will
but there ain't no guarentees
i'm major in love
but in all minor key
'cause falling in love is so hard on the knees

what are you looking for
it's got to be hard core
must be some kind of nouveau riche

is this your only chance
or some hypnotic trance
let's get you on a tighter leach

you're so bad, you're so bad, you're so
you're so bad, you're so bad, you're so

you ain't that good

down to the letter
but you like the way
i hold the microphone
sometimes i good but
when i'm bad i'm even better
don't give me no lip
i've got enough of my own

there ain't gonna be
no more beggin' you please
you know what i want
and it ain't one of these
you're bad to the bone
and your girlfriend agreed
that falling in love is so hard on the knees

i'm jones' in' on love
yeah i got the dt's
you say that we will, yeah
but there ain't no gurantees
i'm major in love
but in all minor key
'cause falling in love is so hard on the knees
