When you have Kelly Ripa as a mom, you better hope to have amazingly funny memories she can share on television, for better or for worse!

In a recent appearance on The Late Show with Stephen Colbert, Kelly shared a specific moment with her son that involved Stephen’s 2012 book, I Am a Pole (And So Can You!), the story about a pole trying to finds its purpose in life — at one point, it goes to a strip club but quits because it “couldn’t stand the grind.”

“I have a bone to pick with you about a book you sold on our show,” she said to Stephen. Apparently, her son Joaquin had taken the book to school the morning before for his teacher to read. “He goes to school where the primary focus of the education is really learning how to read. If you master so many books, you can bring in a book of your choice and the teacher will read the book out loud to the class… He sends it back to me and says, ‘The teacher wouldn’t finish reading the book.”

Joaqin’s teacher ended up writing a note to Kelly, saying that while the book was funny, it quickly became inappropriate for 9-year olds. But don’t worry, she has no ill-will toward Stephen’s writing.

“This is still the greatest school memory we have,” she said. “Nowadays, parents are so careful and they’re so good at parenting and I became that mom.”
