As a 9 year old I remember seriously (but unintentionally) disrupting an assembly at Monkwood Junior School when I simultaneously threw up and shat myself.
At Mexborough Grammar School, one 'tactic' was the volume of singing in certain hymns/songs. e.g. Oh Come All Ye Faithful (which for some reason we sang in Latin). The repeated 3 line chorus (Oh come let us adore him.....Venite adoramus in our version) was supposed to be sang in crescendo, starting quiet and increasing so just for fun we whispered the first 2 lines and yelled the last as loud as we could. Same tactics for the school song. Nobody knew most of the words so just mumbled along until the final line when everyone then joined in with "Where the white rose blows and youth calls, by Don and Dearne". Obviously had an impact as I still remember that line 50 years later
