I find it very odd that CS graduates don't know C. I don't find it odd that people don't enjoy programming in C. At my univ the introductory programming course is taught using Scheme but there are plenty of course that use C, such as Algorithms and Data Structures and Operating Systems. Hell we even have a course that uses assembly (Computer Architecture). This is all on the undergrad degree.
