"I was taking a shower and the door got locked/jammed," he explained on Twitter with this photo of the door after he broke through. "With no phone to call for help, I used my bobsled push training to break out."
And just a few days later, he got stuck again...this time in an elevator!
"No one is going to believe this but we just got stuck in an elevator," he Tweeted on Feb. 10 with a pic of himself trying to pry the doors open.
Luckily, he escaped but Johnny says he won't take chances getting stuck again on his big day.
"You can make sure that on race day I'll make sure that I shower with the door open and probably take the stairs," he told Piers Morgan.
