Those are the words written in the margins of one of my barbri handouts. I didn't think about the phrase that prompted this response while I was writing it down, but when my friend to my left pointed it out, I realized it's times like this that illuminate why lawyers are fucked up.
I had written, "valid trust as long as W had a vasectomy."

I told my partner in crime that the reason why he didn't understand future interests and the Rule Against Perpetuities is because the "life in being" that he drew on his outline was ugly. He was busy jazzing up his stick figure with a baseball hat, a gun, and a beer when the discussion of vasectomies ensued.
