There are some New Yorkers (like me) who usually do not pronounce the "h"-like sound (essentially a palatal fricative) that most English speakers have at the beginnings of words whose first vowel is the high-back-rounded "u" (words like "Hugh" and "Huron" and "human"), pronouncing those words much like ("you" and "you're-on" and ... "yuman"). Also, some New Yorkers have a second person plural pronoun that is different from the standard "you" and is different from the southern "y'all". The New Yorker in this story has both of these linguistic traits. Okay, now that that is out of the way....
A New Yorker is conducting an art class at the University of Michigan in which the only two students are Hugh Downs and Hugh Grant. The students today are learning to draw animals and are taken, in order to draw and paint on location, to the site where the researchers in endocrinology are doing studies on sheep. (The University, I believe, did in fact have a small farm-like area where they raised sheep, the black-faced kind, in order to study hormones and the like.) Okay, work with me here... The students want to take creative license and paint the sheep with whatever color they choose. The instructor tries very hard to explain that a main part of today's exercise is practice in the mixing of colors to match exactly what is seen. An argument ensues. Hugh Grant wants to paint the sheep purple, thinking it would be humorous (or should I say "yumorous"), while Mr. Downs being color-blind, as everyone in the world knows (except, evidently, the instructor), is somewhat confused as to what color to employ at all. Finally, after much discussion, the instructor pulls rank, states the law and says:
