Bill Turnbull caused upheaval in the Good Morning Britain studio when he lost his earpiece during the live show.
The 64-year-old TV presenter - who has been standing in for Piers Morgan on the ITV breakfast show - made sure he went out with a bang on his last day by bringing GMB to a stand still in the hunt for his missing earpiece.
Co-host Susanna Reid, 49, told viewers: "You know they call Wednesday 'Hump Day' - Bill is really having one of those Wednesdays. You'd forgotten to put your teeth in earlier and were having trouble reading."
Not sure what to say about this, other than thank you to everyone @gmb - crew and producers (not forgetting @susannareid100 for making me feel so welcome this week. It's been really lovely 😍 https://t.co/Y0Z201mHLe
Turnbull agreed: "And I've forgotten my contact lenses and I'm having to wear glasses. And then my earpiece popped out and we can't find it."
A clip was shown of the entire GMB production team searching the studio floor during the ad break for Turnbull's inner earpiece, used for producers to communicate with the hosts during the show.
