Not many people could get away with making a joke at Roy Keane’s expense.
But Ryan Giggs, who played alongside the fearsome Irishman at Manchester United for 12 years, is one of them - as was evident after the Euro 2016 semi-final between Portugal and Wales on Wednesday evening.
Giggs was asked about Wales' chances of qualifying for the 2018 World Cup and responded by saying: “Well, yeah, it’s a nice easy group…” and then immediately turned, with a smile on his face, to Keane. (Scroll down to watch the video below).

Keane is, of course, the assistant manager of the Republic of Ireland, who find themselves in Group D alongside the Welsh.
Had anyone else made the comment, there would have been a high chance of Keane flipping out.

But as it was Giggsy, even Keane had a smile on his face and reacted by slapping the knee of his former teammate.
Giggs, on a slightly more serious note, then added: “No, it’s going to be difficult.”
World Cup qualifying will be hard for both teams
Wales will head into the World Cup qualifiers full of confidence after their remarkable run to the Euro 2016 semi-finals.
But qualifying for the 32-team tournament in Russia will be significantly more difficult than securing a place in the European Championships.
Only the top teams in each group directly qualify for the finals, while eight of the nine best runners-up enter the play-off round.
Wales and Ireland also find themselves up against Austria, Serbia, Moldova and Georgia.
The Welsh bowed out of Euro 2016 following a 2-0 defeat to Portugal, who booked their place in the final thanks to goals from Cristiano Ronaldo and Nani.
Coleman proud of players
"It hurts that we lost the semi-final, the players are gutted, but they need to look back and see they have done their country proud," Wales boss Chris Coleman was quoted as saying by Sky Sports. "They could only give what they had and we looked a bit tired tonight.
"We never really found our momentum when we had possession, but you have to give Portugal credit, they defended deep and killed our space."
He added: "That first goal was going to be crucial. We just lost our concentration for five minutes and when you are up against quality in the semi-final of a tournament like this, Portugal unfortunately capitalised on that.
"We've done plenty of winning. Tonight it is our turn to lose, but congratulations to Portugal and I hope they go on to win the tournament.”
