Beer

Michelle: "What color are your toenails?"

Lizzy: "Blue."

Jay: "They match the flower in your hair."

Lizzy: "My planned that."

Michelle: "Very nice."

Lizzy: "They match your necklace."
Michelle, handing Lizzy her necklace: "Here Lizzy, you can have it."
Lizzy: "No, that spells beer."

Michelle: "So you can't wear it?"

Lizzy: "Nope."

This is the "beer" necklace.
