OH this is so, so priceless. Not only does it make references to yaoi and fanfiction, it also have the two male leads re-enacting a cheesy romantic scene in a fanfic.
Skip to 1.40 for the main action.
PS: Oh by the way, have anyone of you caught Rob-B-Hood? Daniel Wu (and Nicholas Tse) has a hilarious cameo as a rather dumb driver who is superbly gay.
Edit: I just found out from a friend that one of the guys in the band above (DBSG) was hospitalised after he drank a glass of water laced with superglue. It was given to him by an anti-fan. Horrible huh?
