takes one to know one lyrics – katy perry

what are you looking yeah
i saw this coming from a mile away
i saw a crack in the egg
a little rip in the page
i found your necklace on the floor
underneath the bed
where you said
i was the only one…

you thought i’d cry
you thought i’dcry
you thought i’d lay down and die
you thought there’s no getting over you
ha ha…

and all this time
all this time
you’ve been having your fun
i’ve been having some fun too…

cause it takes one to know one
congrats you’ve met your match
you think i’d lie here heartbroken
but the knife is in your back
in your back…

you left your suit you left your tie
and looked me in the eye
and swore that it was business baby
yeah right…

and when you left i got a call
that started it all
and now it’s not your business baby
you thought i’d cry
you thought i’dcry
you thought i’d lay down and die
you thought there’s no getting over you
ha ha…

but all this time
all this time
you’ve been having your fun
i’ve been having some fun too…

cause’ it takes one to know one
congrats you’ve met your match
you think i’d lie here heartbroken
i’d lie here
but the knife is in your back
in your back…

you’re such a wreck
the cutest accident
makes so much sense
you’ll come back to me oh…

and i’ll let you
hey
huh
you’re back…

cause it takes one to know one
congrats you’ve met your match
you think i’d lie here heartbroken
i’d lie here
but the knife is in you’re back
in yourback…

cause it takes one to know one
hi nice to meet you
congrats you’ve met your match
you think i’d lie here heartbroken
i’ll lie here
but the knife is in your back
in-your back…
