This happpened in my country, Argentina.
Mauricio Macri, Buenos Aires' mayor, is a well-known Queen fan. During his wedding party, he dressed as Freddie to sing "Love of my life" to his bride. Somewhere in the middle of the song, he choked on the moustache when he took a breath. He had to be assisted by a doctor, who gave Macri some water and told him to try to swallow the moustache, as he was unable to spit it out.
The party went on amidst laughter, and some guests joked: "This is Freddie telling him to stop singing!"
