Basil Fotherington-Thomas is a classic fictional character in a series of books by Geoffrey Willans and Ronald Searle starring the archetypal English prep school boy of the 1950s, Nigel Molesworth, who is the supposed author.
Nigel is a schoolboy at St Custard's, a fictional (and terrible) prep school located in a carefully unspecified part of England. Nigel's spelling is extremely uneven, a feature found endearing by fans. This extends to Fotherington-Thomas's name: Nigel always misspells it 'Fotherington-Tomas'.
Whilst Nigel epitomises the worthy inky and earthy school boy, Fotherington-Thomas is the opposite, being an effete and loathed sissy. Fotherington-Thomas is reported to bear a certain resemblance to Little Lord Fauntleroy; whilst he is also a student at St. Custard's school, he is regularly dismissed as a being a 'gurl' and a sissy by Molesworth due to his curly blond locks and his questionable tendency to skip around the school saying such things as "hullo clouds, hullo sky". In several footballing scenes in the books, Fotherington-Thomas plays in goal. He is a surprisingly talented tennis-player.
