"Ooooh Betty" - Frank Spencer is back!
Michael Crawford is reprising the role for a Sport Relief special of Some Mothers Do 'Ave 'Em, almost 40 years after the end of the classic series.
Michele Dotrice is also returning as Frank's famous wife Betty.
The sketch will show hapless Frank encountering the usual calamities before he eventually meets Sir Bradley Wiggins by chance at the Lee Valley VeloPark - with hilarious consequences.
"I am thrilled and delighted to have been asked to bring Frank back for Sport Relief," said Michael Crawford, while Michele Dotrice added: "It will be an absolute joy to be reunited again with Frank and fitting, for it is such a wonderful cause."
Sir Bradley Wiggins said: "I am a huge fan of Michael so it's an absolute honour to be asked to be involved alongside such an icon of British television… and all for a great cause!"
The sketch will be shown as part of the BBC's Sport Relief coverage on Friday, March 18 on BBC One.
