Primo buddy, I noticed this a week ago and was told not to tell me, but I now feel that your failure is my responsability.
Your signiture is
1. Not original
2. From Bo Burnam's song "New Math"
3. Horribly wrong
What it says:
"Girls are like square roots. If they're under 18, you just gotta do them in your head."
What it should say:
"Squaring numbers is just like women, if they're under 13 just do em in your head"
Now I'm no math wiz, but numbers under 18 with clear square roots are actually quite easy to do.
