Thankfully, the interruption came during the middle of a segment about Theresa May’s attempts to get her Brexit deal through parliament.
During the confusion, Dan started tweeting about the technical issues, jokingly blaming them on a ‘flux capacitor’ - a reference to the engine that ran the time machine in the classic 80s movie ‘Back To The Future’.
He said: “Can you see us on BBC1? Have we gone somewhere? Can someone put the plug back in?”
When the show eventually returned, he said: “We’re back. The flux capacitor is working again.”
The ‘GMB’ host took delight in his rival morning programme’s plight, commenting: “Just hearing that our rivals at BBC Breakfast have had the plug pulled on them.”
Susanna Reid replied: “I can’t imagine who might have done that.”
Piers said: “We don’t know for how long but apparently it took a long time for anyone to realise.
“If you’ve been watching the BBC and you’re obviously bored - or maybe you’re finding the blank screen more interesting than their normal fare - come over here. We have power here in every sense.”
The mocking quickly spilled onto Twitter, with Piers asking Dan: ”Cut off for being too boring?”
Dan immediately hit back with: “Our black screen still had double your audience.”
Dan and Piers have long had a (mostly) playful rivalry over which of their morning programmes are the best.
Both ‘BBC Breakfast’ and ‘Good Morning Britain’ air weekdays at 6am.
