Some say he has an allergic reaction to the word "fracas"... and that if you don't warm his food properly, he'll punch you in the nose. All we know is, his last episode of Top Gear will air on BBC Two on 28 June at 8pm.
The 75-minute special will draw the curtain on 12 years of Clarkson, Hammond and May, following the trio on the final two location shoots that were filmed before the now-infamous producer-harming events that saw the remainder of the most recent series pulled from production. Will it be a classic, fitting end to the series? Probably not, given the broken format of the show: the studio links will feature only Hammond and May, with a notable absence of sniggering studio audience and befuddled Clarkson.
Andy Wilman, the show's former executive producer, told the Radio Times that the show is set to finish things off on a poignant note - rather than a racist one. "The final session without Jeremy was very poignant," said Wilman. "We’ve had a lot of fun in that studio, but we had a job to do and we got it done, professionally, and without tears or tantrums."
Filmed before Chris Evans was officially announced as the new lead presenter of the show, don't expect the new host to make an appearance at any point. Instead, you'll be in for a task which sees the original trio immerse themselves in the lifestyle of the traditional classic car enthusiast, while the second film sees them take some affordable motors on the road as "lifestyle leisure enthusiasts".
It's not the end that Top Gear fans will have wanted - but the 12-year-old ship has been creaking in recent series, with the once-natural banter of the trio drying up in favour of scripted, controversial spectacles. A new set of presenters could bring a much needed change of gear, away from casual xenophobia and into new grounds of casual car entertainment.
Here's hoping the new series will be able to match the likes of these classic moments.
