Explain SMBC — the wiki for Saturday Morning Breakfast Cereal

This single-panel comic shows a man grinning and saying "You know what else is double standard? My penis." The caption below reads: "I'm no longer allowed in Women's Studies class."

The joke operates as a quick, crass punchline built on a double meaning. In a Women's Studies class, "double standard" refers to the serious sociological concept of unequal rules applied to different genders -- for example, how promiscuity is judged differently in men versus women. The character hijacks the term to make a juvenile innuendo about his anatomy being "double standard" (i.e., twice the standard size), completely derailing an academic discussion with a crude boast. The humor comes from the obvious social inappropriateness of the remark and the predictable consequence of being banned from the class. The comic satirizes a certain type of person who shows up to serious discussions about gender issues only to make them about themselves in the most tone-deaf way possible.
