You, you, you, you   [x4]      You, change your mind   Like a girl changes clothes   Yeah you, PMS   Like a bitch, I would know      And you over think   Always speak critically   I should know   That you're no good for me      We used to be   Just like twins   So in sync   The same energy   Now a dead battery      used to laugh, bout nothing   Now you're plain boring      I should know, that you're not gonna change      Cause you're hot then you're cold   you're in then you're out   You're up then you're down   You're wrong when it's right   It's black and it's white   We fight, we break up   We kiss, we make up      (You!) You don't really wanna stay, no   (You!) You don't really wanna go-o      You're hot then you're cold   you're yes then you're not   You're in then you're out   You're up then you're down      L-M-F-A-O   Someone call the doctor!      Somebody call the doctor   Nice to meet you I'm doctor poo   And ima tell you two what you got to do   Communication is key   And that's what the problem seems to be   Katy, ya man kisses hot n cold   What ya gotta understand that he's on the road   Performin every night livin show to show   Being out on the stands where you need to grow      Foo, you gotta show that ya care   Not just smackin her ass and pullin her hair   Take her to dinner   Take her to a play   Show her you love her      Do that? Gay!      It's not like you need something special everyday   You can work it out, work work it out   Work it out, work work it out   Work it out, work it out      Work it out, w-work it out   Work w-w-w-w-w-w-work it out   [x4]      You, on my mind   All the time   Like my fro (work work it out)   And girl, I love you   More than you'd ever know (work work it out)      But why do you always   Need attention when I'm hangin' with the gang   Jesus christ! I'm sippin' on a brew!    And I'm tryin' to watch the game!      Cause you're hot then you're cold   you're yes then you're no   You're in then you're out   You're up then you're down      You're wrong when it's right   It's black and it's white   We fight, we break up   We kiss, we make up      (You!) You don't really wanna stay, no   (You!) You don't really wanna go-o      You're hot then you're cold   You're yes then you're no   You're in then you're out   You're up then you're down
