Sir David Jason had a "seriously bad" case of coronavirus this summer, so much so he collapsed and couldn't get back up.
The 'Only Fools and Horses' legend has told how he fell against a radiator when he was suffering from COVID, but he didn't have the strength to pull himself back up.
He said: "I got it seriously bad. Because all the muscles weren't working, I collapsed and I fell against the radiator ... I was so weak, I couldn't get up.
"I crawled to the bed. The muscles weren't working and I used the bed to try and stand up so that I could go to where I wanted to get, and also get back into bed, and I couldn't ...
"I tried for about a quarter of an hour, trying all sorts of things to stand up so I could walk about."
David - who is known for playing Del Boy Trotter in the iconic BBC sitcom - ended up having to crawl along the floor using his head as a lever, which left him with painful carpet burns on his forehead and nose, before his wife Gill Hinchcliffe eventually came to his rescue.
Speaking on 'BBC Breakfast', the 'Open All Hours' actor added: "My arms wouldn't work and my legs wouldn't work, so being a very creative and inventive person, I thought, how will I get from here to the door?
"You know when you see a walrus if you watch David Attenborough, and they walk on land, they crawl on land? That's what I did.
"But in order to do that, I had to use my head. So now I'm lying face down on the ground, and in order to get to the door - and the arms really weren't working and the legs weren't working - I was using my head to drag me to the door.
"So just as I got to the door, the door opened ... and it was my good lady wife and she managed to help me get back into bed. But later on the next day, I got carpet burns all down on my forehead and across the top of my nose."
