Three chairs

Three Ofsted inspectors visited a very exclusive  Independent Girls school. 
 
In an extensive programme the Inspectors decided to attend a morning Assembly. Here, the Head introduced the Inspectors to the girls and then quickly realised that  whilst there were sufficient chairs for members of staff seated on the stage there were no  seats for the Inspectors. 
 
In a brisk fashion The Head then clapped  her hands and with some urgency said
“ Three Chairs” for the Inspectors.   
 
Whereupon a significant number of girls  in the hall responded by shouting “Hip ‘ Hip’  Hooray ‘“.
