daniel henny and binnie's skinny ex are perfect in my name is kim sam soon. the shoe designer friend in i need romance 2 is good. there are a few instances in i do i do.
however, anytime a character is said to have good english or brags on thier own english it is nigh unintelligible. my personal favorite is Hyun Bin in the snow queen. it's esp. funny b/c he's mockign another dude's english, and when you hear other dude talk it's obvious he lived in the states. his english is damn near perfect.
also just for kicks, Kim Hyun Joong from SS501 sounds like some one making fun of a swedish person speaking english.just watch the 1st 20 seconds or so.
