Capo 2nd fret

Standard (EADGBE)

Intro

x2

 You're insecure, don't know what for

 And 2 is half of 4

 And two 3s, that's fun for us

 Cause we're young and we can still remember stuff

Everyone else can multiply by 60

Everyone else can add 2

 So take of 100 and add on 24

 Then divide by 2 and add on 7 more

 And if you're struggling now it's not hard to tell

 You don't know, your math skills are terrible

If only you had a mind like me

 You'd understand how to divide the sum by 3

 Then add on the age of an OAP(+60)

 You don't know, your math skills are terrible

 It's really kind of pitiful

Just a side note; if you're wondering what the answer is, it's 130. :)
