They did this themselves.... only our boys xD
ON MY NOBLE STEEDS TO LE LYRICS:
[Liam] You're insecure
So half of four
Your old brains are not what they were before
[Zayn] Add two threes. Its fun for us
'Cause we're young and we can still remember stuff
[Harry] Everyone else can multiply by sixty
Everyone else can add two
[All] Now take off one hundred, and add on 24
Then divide by two and add on seven more
And if you're struggling now its not hard to tell
You don't know, oh, oh, your math skills are terrible
If only you had a mind like me
You'd understand how to divide the sum by three
And then just add on the age of this OAP
You don't know, oh, oh, your math skills are terrible, oh, oh
[Harry] Its really kinda pitiful
