Most notable of all the cameos is the orthologist guy! Sadly, our "hero" in this movie doesn't have a pervy best friend. Or, seemingly, any friends. Given his stalker-y behavior though, maybe that's not too surprising.
Also, sex scenes in bikinis! Shots of TV screens!
People sitting at nicely appointed dinner tables!
Awkward dates in non-specific restaurants that move to a beach and then to famous San Francisco landmarks!
Silent exclamations of joy to one's self!
All of the classing Nguyen elements are here!
