Bentley could not think of anything more annoying than how the girls at Hogwarts oogled at professor Hirsch. It was truly nauseating. What was so special about the man anyways, with his perfect stupid hair and perfect teeth and face hair? He just didn't get it and probably never would.

It therefore gave him reason and ammunition enough to work with Blaise in getting the flyers done. The only reasonable explanation was that the man and the other professors had been spiking their food source..altering the behaviour of the students, especially the girls. It was therefore up to them to save the school's student population.

So, the third hair charmed the poster stuck to the professor's door and moved on to the next one.
