My friend has a teacup Yorkie that does the same thing. She tries to wriggle into your lap and then lays out between your thighs, and looks at you expectantly. If you stop scratching and pick her up, she throws her head back violently to indicate her intent.

That little loris was incredibly cute...but I have to wonder what that dorm room smelled like, with an animal that "marks its territory with urine... constantly... for the span of its entire life."
