Murray Walker: 'I used to eat cat food'
The former motorsports commentator told the Daily Express that he used to taste the cat food in front of sceptical clients to prove its quality.
Walker said: "I used to sell pet food and if they were suspicious about the quality and they queried it, we would open the can of Kitekat and eat it in front of them."
Before rising to fame as the voice of Formula One on the BBC and ITV, the 87-year-old managed accounts for clients including Dunlop and Vauxhall Motors.
Walker is often erroneously said to have created the slogan "a Mars a day helps you work, rest and play". However, he did pen the tagline "Trill makes budgies bounce with health" in the 1960s.
Although he officially retired from Formula One commentary in 2001, Walker covered for BBC Radio 5 Live's David Croft at the 2007 European Grand Prix when he took paternity leave.
