The tome, titled A Promised Land, was released on Tuesday, and has already sold more than one million copies when audio book sales are added to the count.
And while many have praised the detailed autobiography, others have been left stunned by the fact it will take them more than an entire day to listen to it.
Fox News pundit Tucker Carlson chimed in during a segment on his show Thursday night, pointing out that A Promised Land – which is 768 pages long – is the second memoir that the former president has written.
Obama, 59, previously penned the 1995 bestseller, Dreams From My Father: A Story of Race and Inheritance.
‘Two autobiographies before you’re 60? It’s safe to say he doesn’t have a self-esteem problem,’ Carlson tartly stated.
Obama is now in the process of writing a third memoir, which will detail the later part of his presidency. It will be released sometime in the next few years.
Barack Obama has been described as an ‘ego maniac’ after it was revealed that the audio book edition of his new memoir runs for a whopping 29 hours. Tucker Carlson and his guest Adam Carolla poked fun at the former president in a segment Thursday night
On Twitter, the former president has been described as ‘self-centered’, a ‘narcissist’, and ‘a legend in his own mind’ over the lengthy run time
Meanwhile, comedian Adam Carolla appeared on Carlson’s program and stated: ‘Obama is a bigger narcissist than Trump!’
‘I was only able to listen to the first 17 hours on the toilet this morning,’ he joked.
On Twitter, the run time of the A Promised Land audio book also sparked a flurry of tweets.
‘@BarackObama’s memoir is 29 hours on @audible and it’s only the first volume covering just his first term. @MichelleObama’s covers her entire life in 19 hours! What’s Barry so long-winded about?’ one asked.
Meghan McCain’s husband, Ben Domenech, also chimed in, stating: ‘I realize 19 hours of Barack Obama talking about himself may seem like a problem, but don’t worry, it’s just Volume 1.’
However, others are thrilled to be listening to Obama for hour after hour.
’19 hours of pure bliss,’ one cooed.
Another wrote: ‘Just used my crisp new Audible credit to buy the new @BarackObama book and it’s 29 hours of that voice, you guys. TWENTY-NINE HOURS. Whatever is ailing me will surely be cured by the end.’
