The story
Attested in 1968, but probably popularised by footballer Robbie Fowler who, after scoring four goals in a Premier League match against Middlesbrough on 14 December 1996, revealed a T-shirt with the phrase written on it in marker pen. He explained to the press that it was Happy Mondays percussionist Bez's catchphrase in his segment "Science with Bez" on BBC Two's The Sunday Show (1995–97).
