 Am    (Strum periodically) 
When, a song, is stuck inside your head,

 Am                                            Em
Sing, this song, just sing this song instead. Again now,

 Am
When, a song, is stuck inside your head,

 Am                                              Em
Sing, this song, just sing this song instead. It goes like,

(Chorus)

Just do that for every verse, and your good!

When you done, don't forget to drink some hot kool-aid and malk.
