"She Makes Me Laugh"

I listened to Good Times! yester-day and noticed a small feature in "She Makes Me Laugh."  In the line "And I would like to be with her for a while," "while" is sung with a melisma (C# B A), providing a sense of duration.

When I referenced the lyrics, I also noticed that the line "She's fine as any valentine" exhibits internal rhyme.  To some degree, this additional rhyme mirrors the narrator's high regard for the girl.
