McMurphy:  She was fifteen years old , going on thirty - five , Doc , and she told me she was _ eighteen _ , she was very willing , I practically had to take to sewing my pants shut . Between you and me , uh , she might have been fifteen , but when you get that little red beaver right up there in front of you , I do n't think it 's crazy at all and I do n't think you do either . No man alive could resist that , and that 's why I got into jail to begin with . And now they 're telling me I 'm crazy over here because I do n't sit there like a goddamn vegetable . Do n't make a bit of sense to me . If that 's what being crazy is , then I 'm senseless , out of it , gone - down - the - road , wacko . But no more , no less , that 's it .
