A former teacher has been struck off after a panel heard he told one pupil he would only attend the school show if she was wearing a "low-cut crop top and tight trousers".
The General Teaching Council Scotland (GTCS) held a hearing into allegations against John Kerr while he was employed at Berwickshire High School teaching history and modern studies more than seven years ago.
The 75-year-old denied the claims and said the conversation had not happened.
However, the panel found the allegation had been proved - along with a number of others - and concluded he should be removed from the teaching register for a year.
The case dated back to December 2018 when Kerr had been working at the secondary school in Duns in the Scottish Borders.
It was alleged that when asked by Pupil B if he would be attending the school production of Grease he had said words to the effect of: "I will if you are going to be wearing the low-cut crop top and tight trousers, but I might not have a job the next day."
Kerr said he had not been aware of the production and had been away in Seville for 10 days at the time.
The hearing also concluded that he had - in February the following year - shouted at Pupil A, spat on his own hand and wiped it on the pupil's arm and pushed the student.
'Thick and stupid'
A claim was found not to be proved that he had told another pupil: "I am going to burn you."
Kerr told the hearing he had not used the phrase which sounded like it had been taken from a comic.
A string of other statements made to Pupil C were found to have been proven.
They included: "You'll never be as smart as me ... I have written over 50 books."
He was also found to have said: "You are thick and stupid ... you will never make anything of your life."

A representative for Kerr told the hearing that as the teacher was now 75 he had no plans to return to the profession.
The panel said it took into account that the events had taken place about seven years ago and that he had not returned to the classroom since shortly afterwards.
However, it found the conduct was "very serious" and involved multiple pupils in three separate incidents and "displayed a pattern of concerning behaviour".
The teacher's representative submitted that no sanction was necessary but the panel concluded removal of his registration was "the appropriate and proportionate sanction".
It decided he was unfit to teach and ordered that he be taken off the register for a period of one year.
