Ha, virtually none. I have 1400 students, about 600 of whom I have classes with, the remainder who run screaming and grabbing at my legs in the hallways. There are a standout few who really make themselves known - A wonderful example being a boy named 이호식 - Lee Ho Shik. He is very fat, and one day I was astounded to hear my KT call him Ho Shik I (in Korean, no "L" sound). I asked why she called him that, and she told me it was his name. She had, as all the students and teachers do, westernised his name and put surname last. The catch is, here in Changwon, and I'm not sure where else, there is a chain of fried chicken takeaways called Ho-Si-Gi, same sound as his name. So, yeah, we have a fat kid named "Fried Chicken." Obviously, I'm never gonna forget him. He's awesome, never lets teasing or jokes upset him, and is a complete class clown, always dancing around, making jokes, smiling and laughing, and fantastic manners.
As for the others... I have a trick which always gets me off the hook when they come running at me, asking "Teacher, do you know my name?" I look at them, pretending to concentrate, and hesitantly, answer with any 3 syllable Korean word or phrase I can remember at the time. My favourites are 쿤멍키 (Big monkey), 이상한 (strange, weird), 틍틍해 (fat), 지르한 or 심심한 (boring). Anytime that I happen to have another in my head I'll drag that out. Once I say the word, their friends all start chanting the word, and I slip away having dodged the onus of actually answering the question. Great fun, I also apply it to random kids on the streets if they do the same.
