[Verse 1]
Something weird's going on 'round here
Gotta get me some evidence
Some strange goings-on happen on the back lawn
And it's gettin' too intense

[Chorus]
'Cause you're not Ferb, no
And I'm disturbed
'Cause you're not Ferb

[Verse 2]
You've got the same colored hair and his savoir-faire
And his zany serenity
Though it's not conclusive something elusive
Says you stole his identity

[Chorus]
'Cause you're not Ferb, no
You're not Ferb, no
You're not Ferb
You're not Ferb
You're not Ferb
You're not Ferb
You're not Ferb
You're not Ferb
You're not Ferb
