Meeting someone on a plane?

A man takes his seat on an airline flight and he is seated next to an attractive younger women. During the flight she pulls out some paper work, they chat and she is grad student working on masters thesis. She explains she is comparing the physical differences between ethnic groups. She states, "Right now I am on the chapter dealing with the male member and how the size varies by region." She gives him a wry smile and he gets a little red faced. So he trys to play it cool and asks....So what ethnic groups have the largest members. She states that would the Polish and Native Americans. Uhm he says. She then introduces herself.....I am Mandy Jeffers, he says without hesitation.....Nice to meet you....I am Running Bear Kowalski.
