'let me in, let me in...' bash bash bash... french teacher after someone locked him out of the classroom one april fools day
actually,
'come on, own up, which one of you did that? If you don't own up then the whole class is in for detention'
was more like his catchphrase coz pretty much every lesson he'd have a'kick me' sticker stuck to his back, or someone would have glued the register to the desk, or the entire class would have agreed that nobody was going to speak when he asked us to 'repeat after me...' etc. etc.
we were quite merciless tbh when I think about it
