"Kyke" (Seth) seems to impart the bizarre idea that cancer could actually help you "meet some girls". Adam buys it. But he seems to already "have one". It seems, though, that the female therapist is a hoarder and Adam has to help her get rid of "this mess" in her car.
Early in the film, Adam mentions "Terms of Endearment", a famous 1982 Paramount film (I saw it in Dallas) directed by James Brooks; toward the end, a character learns she may have cancer when I doctor notices enlarged lymph nodes when giving a shot; the film progresses quickly to a tragic end. No so here, though. But Adam is very blunt in the way he tells his family, "I have cancer".
