Brave teachers allowed pupils to shave off their facial furniture to mark the end of Movember.
The 14 teachers, at Heckmondwike Grammar School, took part in the moustache-growing month to raise cash for men’s health charities.
And they auctioned off the chance to shave off their ‘taches to eager pupils at the end of November.
Deputy headteacher Peter Roberts said: “To help promote greater awareness of men’s health issues, 14 members of staff cajoled, persuaded, even bullied each other to grow moustaches for the month of November.
“While some of the younger members of the team were trying various forms of growth enhancer to achieve the desired effect, the older members were saddened that their ‘taches had grown back grey since last year and now resembled retired RAF sergeants or in one case, more than a passing resemblance to Joseph Stalin.
“Having spent a month being cold shouldered by their partners, the team then took their life in their hands by being auctioned off to student bidders who wanted to shave their favourite teacher during a big shave-off on the stage in the packed Swann Hall at lunchtime.
“The students, all wearing fake moustaches, were entertained by the staff’s shambolic dance moves to the Village People’s YMCA, before the students voted for the Mo-Bro of the year using the highly sophisticated ‘cheerometer’.
“The 2013 champion was Mr Shires who had gone for quantity and not quality with his facial fuzz.”
The staff raised £500 through sponsorship and selling moustachioed buns and knitted moustaches.
Mr Roberts added: “It was a great achievement and a good bit of fun at the same time.
