Verse: 
 
G              C                                             D       Em       
My baby dont mess around because she loves me so and this i know fo sho 
 
G              C                                              D        Em 
But does she really want to?  But can't stand to see me walk out the door

Dont try to fight the feeling cause the thought alone is killing me right now 
 
G              C                                               D        Em 
Thank God for mom and dad for sticking two together cause we dont know how 
 
 
Chorus: (x4) 
 
G          C     D        Em 
Heyyyyyy  Ya!   Heyyyy Yaaaaaaa! 
 
 
 
its quite simple, and the rest of the song (verse 2, chorus w/ad libs, 
call/response part) 
uses the same chords just listen for the chord changes.  
then theres the breakdown where he goes "shake it like a polaroid  
picture"  then the guitar ropes back in.  this is the song of the year  
so better enjoy.
