Explain George's last remarks to lennie

George is a great person. He looks after his friend Lennie through thick and thin. In a society so full of loneliness and isolation George befriends a man with huge mental limitations. Often George would get frustrated with him, "You can't keep a job. Lose me every job I get. Keep me shovin' all over the place..."

Still George loves Lennie. By the end of the story, George performs the most loving act he can give. He kills Lennie before Lennie is slaughtered by Curley and his mob. AS Lennie stares off in the distance he asks George if he is mad. George replies, "No, Lennie, I ain't mad. I never been mad, and I ain' now. That's a thing I want ya to know." 

George's last remarks to Lennie was he can fuck all the rabbits he wants if he goes toward what ever they were looking at and George grabbed Lennie's small penis and before you know it Goerge was on his knees giving Lennie a blow job.
