Boston Public Library used book spine ‘smack talk’ to defend the Celtics’ playoff loss against Cleveland

The battle between the Celtics and the Cavaliers for the Eastern Conference has begun, and it seems like everyone is getting in on the rivalry.

Yes, that even includes the Boston and Cleveland public libraries, who engaged in some self-proclaimed “smack talk” over Twitter. It all started when the Cleveland Public Library posted this Tweet ahead of Wednesday night’s playoff game:

The photo shows four books placed on top of one another to form a short poem: “Cleveland invasion, Boston, the luck runs out.”

The Boston Public Library countered on Thursday morning with some book spine poetry of their own.

When stacked atop one another, the book spines read: “The Bostonians never back down. The good fight continues Friday.”
