HBO’s “Last Week Tonight" children's book about Vice President Mike Pence's pet rabbit bumped former FBI Director James Comey's highly anticipated memoir from the No. 1 spot on Amazon's best-seller list Monday.

Comey's memoir, "A Higher Loyalty: Truth, Lies, and Leadership," is still a month away from release, but had been No. 1 on Amazon. By Monday afternoon, Comey was bounced by the spoof bunny book, which imagines the Pences' famed Marlon Bundo as a gay bunny.

On his show Sunday night highlighting Mike Pence's "hostility to LGBT rights," Oliver unveiled his own A Day in the Life of Marlon Bundo to coincide with the release of an official book by second lady Karen Pence and daughter Charlotte.

The original book, Marlon Bundo's A Day in the Life of the Vice President, features the BOTUS — Bunny of the United States — as he follows Pence around while he fulfills his duties as vice president.
