One trait of geeks is our ability to earworm quotes.
hominysnark even does a daily "identify the movie quote" contest.
For many of us, it's something we can't turn off. Today at work it kept happening.
An upcoming book has the current (and not likely to remain) title of "Holy Monogamy." The editor kept stressing the second syllable of "monogamy," so that every time he said the title, I mentally added "...Batman!" I was foolish enough to mention this at the table. The folks who are more in my age group giggled. The editor in question clearly had no idea what I was talking about. (Okay, maybe he did, but was totally nonplussed by my interjection.)
Then we were discussing another upcoming book with the (again not likely to remain) title of "Living Together." This time I managed to restrain myself from saying anything, but in the margin of my notes I was compelled to write, "Dogs and cats, living together--MASS HYSTERIA!"
