That's what you bring around some old phonebooks for.
I thought for the longest time I was 5'5". Then we were comparing heights and I was measured at 5'4". Then at a doctor's visit they recorded me as 5'3". Then Rama accused me of shrinking. So I just go by 5'3" now. And I'm the tallest in my immediate family. Not including my dad of course, because he's a whore. He's like 5'8" or something so he's fucking short, too.
