Everything is awesome - until you step on a piece

Prince George just started school, but when he’s off-duty he has a favourite toy that’s familiar to most kids, his dad Prince William revealed on Tuesday.

'Wow, my son would love this,' William said when shown a massive, 280,000-brick model of a McLaren 720S sports car at McLaren Automotive’s headquarters in Woking, Surrey, where the royal dad also got to sit behind the wheel of a real $280,000 720S. 'My son’s very into Lego and he’d love this. It’s incredible.'

Asked about his own interest in cars, William replied, 'I’m a car enthusiast. I don’t know very much about cars but I like speed.'

Then he cut to a critical survival question for many parents.

'The key question is does it have a coffee cup holder?' he said. 'It may be a fast car, but does it have a coffee cup holder?'

Earlier in the day, William — who is on full-time royal duty since leaving his civilian job as an air ambulance pilot at the end of summer — visited Sporting Chance in Liphook, England, an organization that specializes in helping professional and former professional athletes with support for a range of issues including addiction, grief, depression and anxiety. Meanwhile, Princess Kate is still undergoing treatment for acute morning sickness at home at Kensington Palace.
