John Oliver’s satire book about Vice President Pence’s family rabbit has sold out, the late night host said Tuesday.

Oliver said his "Last Week Tonight with John Oliver Presents a Day in the Life of Marlon Bundo” proved to be more popular than he anticipated. The book has sold out in the days since it was announced on his show Sunday night, Oliver told Ellen DeGeneres.

"We were not anticipating people really buying it,” Oliver said. "But they're doing a reprint, so you can still buy it. It'll take a few weeks."

The book parodies the Pence family’s own book about their pet rabbit, Marlon Bundo. That book is titled "Marlon Bundo's A Day in the Life of the Vice President.”

However, the rabbit in Oliver’s book is gay. Pence was criticized for his stance on LGBT issues when he was governor of Indiana.

Oliver’s book is No. 1 on the Amazon best-sellers list as of Tuesday night. The Pence family’s book is at No. 4 on the chart.

Pence’s daughter, Charlotte, said Tuesday that she is “all for” Oliver’s book.

“I think imitation is the most sincere form of flattery in a way,” Pence said during an interview with Fox Business Network's Maria Bartiromo Tuesday. 

“But in all seriousness, his book is contributing to charities that I think we can all get behind. We have two books that are giving to charities that are both about bunnies, so I’m all for it, really,” she continued.

Proceeds from the Pences’ book are going to Tracy’s Kids, a group that offers art therapy to young cancer patients.

Funds from Oliver’s book will be donated to AIDS United, a group dedicated to ending the AIDS epidemic in the U.S., and the Trevor Project, a suicide prevention organization that provides support to young LGBT community members.
