Hand on the buzzer is what tony barber used to say. My geography/social science teacher said this when he realised that we had a bit of dirt on him courtesy of another teacher. Not quite the magnitude of Nepals topsoil exports but dirt none the less. We found out through a teacher that CC had jobbed some bloke at touch football the night before. Of course we couldn't wait till next lesson to have a go at him about this. When we did old mate was a bit flustered and quite embarrassed and said Look at you sitting there with your hand on the buzzer. You just couldn't wait to buzz in and have a go. He was probably right too.
