Late Again Poem by Randy Johnson

(This is a fictional poem)

My wife is late again, what am I going to do?
If she's pregnant, this will make child number twenty-two.
I should've had a vasectomy or she should've had her tubes tied.
We couldn't stop making love no matter how hard we've tried.
I love my children and when they say they love me, it makes my heart melt.
But I can't keep going through this, does anybody know where I can buy my wife a chastity belt?
