Youngest son is home from school with mononucleosis;
But it took a while for us to get this diagnosis.
He complained of headaches first and then he got a rash.
Couldn't get him motivated - all he'd do was crash.
I kept on insisting he get up and go to school.
Didn't want to see my son grow up to be a fool.
Now I'm feeling guilty 'cause the kid was really sick...
Turns out that his mom's the one who's dumber than a brick.
