Well Dan and Mary Smith told me that. He said “What’s the tenth girl?” And I said “I don’t know, what’s the tenth girl?” And he said “Nine out of ten girls are pretty, and the tenth one goes to Michigan.” I guess the girls in Michigan are pretty plain! But, Michigan was a hard school to get into, and you had to be very smart, so it was probably very smart girls but very plain. They told me that in ’76. When we were working at USC together. David’s wife went to Michigan!
(The names above have been changed for confidentiality purposes). This joke has two dynamics to it – a gender differentiation, or a commentary on girls made by boys, as well as a school rivalry component. The informant and his friend who told the joke to him both worked at the University of Southern California, and had a lot of pride and spirit for the school. The friend’s wife went to Michigan – which adds yet another level of humor to the joke, because the joke was told presumably by her as well. At the very least she seems to have been present whenever Dan told the joke. While this is a jab at her appearance (although it could be untrue or unwarranted) it is clearly in a spirit of fun, and relies on stereotyping and blason populaire to make its point and be humorous. The two men clearly respect Mary, and her husband probably finds her attractive, so it seems this joke is told (at least by these specific two men) in a spirit of school rivalry more than anything else. Especially because USC has a reputation or stereotype of attracting a very attractive, but perhaps not as intelligent, female student population.
