oh yar. my brother was doing art/dt/technology somethingorwhatever and they had these huge trays of PVA glue, the one that you can peel off when it dries? Anyway he stuck his hands fac down it, got it all over, walked around laughing at people, walking on desks and jumping over people's heads and stuff, everyone was going crazy, then *gasp* the teacher comes back in!!!!!!!!!!so he scarpers but there's glue everywhere the teacher says 'Who's been mucking with the glue?!' and it sounded so funny...so ...two-sided that everyone burst out laughing, then sam stuck his hand in the air, forgetting it was covered in glue, he said 'WASH THAT OFF NOW YOU STUPID BOY!!!!' and it was a push door which he put two hands flat on and walked off. HAAHAHAHAHAHAHAAAAAAAA. and then his girlfriend peeled all the glue off when he left lol.
