A data mining limerick

Thought you might all appreciate this limerick I wrote today (Merv Adrian said “there must be a limerick in there” and so there was):

My sixteen year old daughter is mild
But the ads she gets lately are wild
I say as her dad
Their computers are mad
Why does Target now think she's with child?
