I Had Eleven Cousins

I had eleven cousins
And one more came to be
Now I’ve an even dozen
For a bigger family
There are 6 on my moms side and 6 on my dads
And, with my neighbors up and down we’re a half a dozen more
That’s a dozen and a half- not counting all the labs
For, with them, we're but six more running in and out the door!
