Reminds me of the Irish world cup team were coming home after a successful world cup, and they apparently arrived the same day as Nelson Mandela. At some point, some of the crowd thought it was the Irish team driving through when it was really Mandela, they didnt stop, they just adapted it and started chanting "Ooh ah Paul McGrath - Ooh ahh Paul McGrath’s da.
lol nice one!
