Writing in his recent Sunday Times column, Clarkson, 61, explained how he had been in Canada when he found himself in the company of a dentist who openly bragged about wanting to kill a polar bear for 'fun'.
Rather than rolling his eyes and mentally crossing the new acquaintance off his Christmas card list, the presenter decided to channel his frustration in a much more, ahem, physical way.
Clarkson waited until the bloke had fallen asleep before he got his own back on behalf of the animal kingdom, recalling: "There are a great many dentists in America - and they're always dentists, for some reason - who like to shoot lions. Or elephants. Or rhinos.
"I met one once, in the frozen wilderness at the top of Canada. He was big in the tooth-whitening business and had taken a 'coupla fun weeks off' to blow a polar bear away.
"I hated him on a cellular level and must confess that one night, when he was asleep, I p***ed in his shoes."
Along with hunters, it seems Clarkson also doesn't have much of an opinion for people who smoke weed.
In a recent interview with LADbible, he said he found weed fans 'boring', and that he usually just ends up going home if people around him are smoking it.
Clarkson, who stars in new Amazon Prime Video series Clarkson's Farm - which sees him attempt to farm 1,000 acres of land in the Cotswolds - said: "We are allowed to grow hemp and things, but I won't because it's so right on and trendy.
"If you're at a party and someone brings a spliff out you just think, 'Christ they're just going to be boring for the rest of the evening.' I usually just go home."
However, it's not just the tedious company that drives him away, as Clarkson also admitted there's also the very real prospect of him pulling a whitey.
"Apart from anything else, if I go into a room and somebody's had a joint I get a white face and pass out.
"Passive dope gives me a serious problem. I just don't hang around with people who partake, put it that way."
Clarkson's Farm was recently renewed for a second series, meaning you'll be able to get another fix of the broadcaster and his farming pal Kaleb.
Offering up a flavour of what we can expect from the next series, Amazon Prime Video said: "Viewers can expect a deeper insight into another year on Diddly Squat Farm as Jeremy aims to diversify, expanding his limited agricultural knowledge under the watchful eye of his no-nonsense team; tractor driver Kaleb, stone wall favourite Gerald, advisor 'Cheerful' Charlie, Jeremy's better-half-turned-farm-shop-keeper Lisa and many more.
"Series 2 promises to bring more laughs, triumphs and tribulations, and of course more farming faux pas, as we follow Jeremy & co on their agricultural adventure."
