Sir Terry Wogan said today he is living a "student" lifestyle - lying in bed watching TV until the afternoon.
The former Radio 2 Breakfast Show host, who has handed over to Chris Evans, said he is now making the most of his freedom in the mornings.
Broadcasting veteran Sir Terry told Absolute Radio: "At the moment we sit there in bed and watch sport. It's terrific because we can be there till one in the afternoon."
The presenter, who called Absolute host Christian O'Connell as part of an on-air competition, added: "Well, I never was a student so I'm making the most of it now - a little too late."
Another BBC host, John Humphrys, also called the show for the Who's Calling Christian? contest in which celebrities phone the station in a bid to win £20,000 for charity.
The Radio 4 Today programme presenter joked: "Listen, don't tell the BBC I'm calling, I'll get the sack. I was given the straight choice of talking to you or my modest 6.5 million audience.
"The Prime Minister, David Cameron and the Queen wanted me to interview them but I said 'Nope, I know where my priorities lie'."
Other celebrities who have taken part in the show so far this week have included Ricky Gervais and Conservative Party leader Mr Cameron.
One caller claimed to be David Beckham today, just hours after he returned to Old Trafford in Manchester United's clash with AC Milan.
But after initially fooling some station staff and listeners, the call turned out to be from impressionist Alistair McGowan.
