In the line "A dancing bear and a circus clown; it's so funny" in "The Poster," the word "funny" is held for more than a full measure (five beats), and this length provides a sense of degree (for "so").
In the line "Oh, I can't wait to see ev'rything there," the three syllables of "ev'rything" are each sung to a different pitch (C# D E), musically giving a sense of breadth.
