Julio is an amateur poet and one of Monica's fellow workers at the Moondance Diner, who she falls for in The One With All The Jealousy. They share a kiss, and she shows the guys a poem he wrote when he was with her called The Empty Vase. Phoebe interprets the poem as Julio using the empty vase of the title as a metaphor to express contempt for Monica; "My vessel so empty with nothing inside. Now that I’ve touched you, you seem emptier still".
