Speaking with Clarkson, Lowe recalls a camping trip where he decided to play an intricate prank on the then-young boys.

“So we went camping, they were probably 8 and 6. I would always tell them stories about Bigfoot, so I decided we were going to the Pacific Northwest where Bigfoot supposedly lives, so I rented a really elaborate Bigfoot costume.”

The actor hid the costume in the Winnebago they drove on the trip and broke it out at night. “I popped out in the middle of the night and walked around the campfire in the distance, making horrible noises.”

Proud of the moment, he adds, “It was so sick, it was the best.”

Clarkson, whose children are currently those ages, says if she did that to her kids they would “never sleep again.”
