Translation: I Don't Know Ken. Who is ken? Ken is not a person and that cannot be reiterated enough; especially when they just reply with 'ken' which is the equivalent of 'I know.' They're not changing the subject by introducing a random person into the conversation and there probably won't be someone called Ken standing behind you. So when you continue to hear about this legend that is Ken, don't ask them who he is because you will get laughed at.
