Pantaloons: Tykes on Poetry

"I score 99 on Jonathan Mayhew's Aesthetic Compatibility Test, and it was easy. I didn't even have to answer the questions once I snuck a look at how to tabulate the score.The result is "a frightening prospect," since I'm almost Jonathan Mayhew. We're matched along 49 dimensions. Our single point of disagreement is that I vastly prefer sneaked to snuck."

You "sneaked" or "snuck" a look?
