Math humor

      Phyllis Diller (1917-20120), outspoken and funny, pioneering female comedian, died Monday, August 20.  Her self-deprecating humor was hugely hilarious -- and it helped the rest of us also not to take ourselves too seriously.

     In honor of Phyllis Diller and humor, I first offer a link to a "poem" from a favorite math-cartoonist -- Randall Munroe offers an amusing rhyming critique of the various majors (including math) available to undergraduates --  at xkcd.com.   And, below, I share several slightly funny math jokes adapted from ones found at Math Jokes 4 Mathy Folks and shaped into 4x4 or 5x5 syllable-square poems.
