"If I see Harman Kardon incorrectly spelled one more time..."

[donquixote99]

Analysis shows two possible explanations:

Known unknown: You know you don't know how to spell Harman Kardon, but you don't care--any guess will be good enough.

Unknown unknown: You don't know that you don't know how to spell Harman Kardon-- Hardon Carmen actually seems right to you.

The only question is which is more common--moderate ignorance combined with apathy, or deep ignorance.
