Shane Warne is a man who knows how to hold a grudge.
The legendary leg-spinner has been at war with another Australian cricketing icon, Steve Waugh for 17 years and counting.
His dislike of his former captain at international level, which flared up in 1999, did not abate over the next five years while the pair were team-mates.
And apparently the subsequent passing of the summers have not mellowed Warne's ire.
Seventeen years. That's longer than World War I and World War II. Combined. It's longer than the Napoleonic Wars by five years.
It's just 99 years short of the 100 Years' War (which actually lasted 116 years).
What was the Waugh crime that so enraged the Sheik of Tweak?
Well, there are lots of reasons, Warne explained while participating in the TV show I'm A Celebrity Get Me Out of Here. But actually there is one reason.
Here's Warne's explanation of the falling out, as reported by Fox Sports News, which will be aired on Tuesday night's edition of the program:
There's a lot of reasons I don't like Steve Waugh ... because he's the most selfish cricketer I've played with.
One thing that really annoyed me about him was the one Test I got dropped, in the West Indies, we had to win the last Test match to win the trophy.
At that stage, captain (Waugh), vice-captain (Warne) and coach (Geoff Marsh) used to pick the team.
We went to selection. I hadn't bowled well, we'd lost, Brian Lara batted unreal, but I felt like I was being the scapegoat, that because I didn't bowl well it was my fault.
We got to the selection table and said, 'OK, what's everyone's thoughts?'. Steve Waugh said 'You're not playing'. I went 'What? Hang on. What do you think the team should be? Blah blah blah', and Steve Waugh said 'Nup, I'm the captain of this side ... you're not playing'.
I was really disappointed with that. After ten years, I'd just had a shoulder operation, I thought the situation, of having to win a Test match, would've brought the best out in me too.
I don't like Steve Waugh for a lot of other reasons, but that was the reason.
