Late in my early teenage, I was considered fast 
While some of the girls were failing, I passed in every class 
Our principal's name was Christian and I played upon his fears 
In exchange 4 my diploma, I loved him through the years 
CHORUS: 
Happy birthday Mr. Christian, what are we gonna do? 
U want a teenage past-time, I want a love that's true 
A man in your position, U oughta be ashamed 
Happy birthday Mr. Christian, why can't U live up 2 your name? 
It was only the first semester but my body developed quick 
Compared 2 the size of my chest then, all the other girls looked sick 
Mr. Christian stared at me always, desire turned 2 pain 
I suggested we go 2 his office and that's when the lunch bell rang 
CHORUS 
Oh Mr. Christian, U're a bad boy 
Why that's not a pencil ... shame 
Oh Mr. Christian, U're a bad boy 
Why can't U live up 2 your name? 
We had our love down to an art form 
Each act was like scenes from a play (Every act...) 
With every lesson I gave him 
Mr. Christian gave me an A 
I graduated with honors 
A riddle 2 everyone 
Everyone except Christian 
Mr. Christian and I, and our son (Mr. Christian, me and our son) 
CHORUS {repeat twice in BG} 
What are we gonna do? 
I want a love that's true 
U oughta be ashamed 
Why can't U live up 2 your name? 
What are we gonna do? 
No tengo tiempo para jugar {I have no time 2 play games} 
Necesito un hombre verdadero, no metido {I need a real man, not a liar} 
Always a man 
Tú sí que no te enteras, chaval, OK? {U don't understand, boy, OK?} 
Qué hacemos? {What are we gonna do?} 
Habla fuerte que no te oigo! {Speak louder cuz I can't hear U!} 
Christian! Christian! Christian! 
Oh Mr. Christian, U're a bad boy 
Christian 
Give me some horns, oh 
I like it 
Christian! {x4} 
Happy birthday 2 U, happy birthday 2 U 
Happy birthday Mr. Christian, happy birthday 2 U 
Happy birthday, Mr. Christian
