From the BBC News article about allegations against Horner

During the presentation, only one moment jarred, when Coulthard made a joke about Horner “getting his kit off”.

It was a reference to celebrations after the team’s first podium finish in Monaco in 2006, when Horner jumped into the swimming pool on the Red Bull barge in the harbour with only a Superman cape protecting his modesty.

But in the light of the allegations swirling around him - details of which have not been made public - it caused eyebrows to raise in the auditorium.
