XYY syndrome is a genetic condition in which a human male has an extra male (Y) chromosome, giving a total of 47 chromosomes instead of the more usual 46. This produces a 47,XYY karyotype, which occurs every 1 in 1,000 male births.
Some medical geneticists question whether the term "syndrome" is appropriate for this condition because its clinical phenotype is normal and the vast majority of XYY males do not know their karyotype.
People with the 47,XYY karyotype have an increased growth velocity from early childhood, with an average final height approximately 7 cm (3") above expected final height. In Edinburgh, Scotland, eight 47,XYY boys born 1967–1972 and identified in a newborn screening programme had an average height of 188.1 cm (6'2") at age 18—their fathers' average height was 174.1 cm (5'8½"), their mothers' average height was 162.8 cm (5'4"). The increased gene dosage of three X/Y chromosome pseudoautosomal region (PAR1) SHOX genes has been postulated as a cause of the increased stature seen in all three sex chromosome trisomies: 47,XXX, 47,XXY, and 47,XYY.
Well, my name it is a number it's on a piece of plastic film
And I've been growin' funny flowers outside on my little window sill
Don't you know I'm a 2,000 man
And my kids, they just don't understand me at all
You know, my wife still respects me even though I really misuse her
I am having an affair with the Random computer
Don't you know I'm a 2,000 man
And my kids, they just don't understand me at all
Oh daddy, proud of your planet, oh mommy, proud of your sun
Oh daddy, proud of your planet, oh mommy, proud of your sun
Oh daddy, your brain's still flashin' like they did when you were young
Or did they come down crashin' seeing all the thing's you'd done
Spacin' out havin' fun
Oh daddy, proud of your planet, oh mommy, proud of your sun
Oh daddy, proud of your planet, oh mommy, proud of your sun

Spacin' out havin' fun
Don't you know I'm a 2,000 man
And my kids, they just don't understand me at all
Don't you know I'm a 2,000 man
And my kids, they just don't understand me at all
Understand me, understand me, understand me
Don't you know I'm a 2,000 man
And my kids, they just don't understand me at all
Don't you know I'm a 2,000 man
And my kids, they just don't understand me at all
I'm a 2,000 man, I'm a 2,000 man
I'm a 2,000 man, I'm a 2,000 man
