Dim is real...dim. He stands at the Korova MilkBar and pulls a glass to drink the drug-laced milk, or as they call it, "Milk Plus". The bar has several statues of naked woman, and the milk comes out of their breasts. Dim goes to "talk" to one of the statues

"Hello, Lucy." "Had a busy night?" "We've been working hard too." "Pardon me, Luce."

He says with a slight chuckle as he places a penny inside the machine to make the milk come out of statue's breast
