Sir Terry Wogan came close to being seriously injured at Friday's Children In Need telethon after a piece of set fell just feet from where he was standing.
The BBC has launched an investigation into the incident, in which a heavy chain dropped from the ceiling.
"It was a huge chain. I heard this enormous crash and I turned around and there was this pile of chain about a couple of feet away from me," Sir Terry says.
Typical of the presenter, he still managed to make a joke about it all.
"With my head, if the chain had hit me it probably wouldn't have made any difference anyway," he added.
"It happened about 8pm in the middle of the show. It is a seven-hour television show, so you just get on with it."
