Okay, the S's:

"--. / ----, / ---- / ------s--'s / ---- / s------- / --- / s--- / s--- / --- / ----- / ------ / ------s, / ---..."

"---- / ---- / --- / - / ------ / ----- / -- / --- / ----, / s--'-- / -- / ----."

Smile and the world smiles with you ... frown and you're just giving yourself wrinkles.
