Well, that all depends on which of the two main definitions for typeface you choose to accept. If you accept the first (most used but least traditional), where typeface and font family are synonymous, then you are right but so am I. If you accept the second definition, where a typeface is a physical "block" that makes the impression of a character set in another media (such as with ink on paper), then you are wrong because Comic Sans is owned by Microsoft and they do not make such devices (if anyone does at all anymore).
Just sayin'.
