Oh man, get this—the first episode of Community my mom ever saw was "Cooperative Calligraphy" (it was mine too).  She didn't catch that they were in a community college, and thought they were in an therapy group, with Jeff as the counselor.  This made the "revelation" even funnier for me.

Hmm, this episode makes me want to rewatch Remedial Chaos Theory… This episode poses an interesting question, and I have a theory that may be the answer. Why would Abed "know" evil Abed?
