Humor and Maths don't seem to have anything in common to nominalists, they do for verbalists.
MATHEMATICS AND HUMOR, University of Chicago Press, 1980. Paper, 1982. Japanese translation, 1983, Dutch translation, 1990. -- In MATHEMATICS AND HUMOR I i} explore the operations and structures common to humor and the formal sciences (logic, mathematics, and linguistics), ii) show how various notions from these sciences provide formal analogues for different sorts of jokes and joke schema, and iii) develop a mathematical model of jokes (joke schema) using ideas from "catastrophe theory"...
I found examples that contradict that maths and humor don't go together here, here and here.
