Mr. Monk Goes to the Circus - S2-E4
Corrected entry: Throughout the entire show, Monk says he is afraid of milk (he says it in "Mr. Monk and the Candidate"). However in "Mr. Monk Goes to the Circus" he asks for milk and cream in his hot chocolate. But in later episodes his fear of milk is still there, so it's not that he's managed to make progress in that area.
Correction: Monk's fear of milk is not based on the taste of milk, but on its texture, and the way it slops everywhere when you pour it. Hot chocolate with milk in it has quite a different texture, and it wouldn't spill everywhere as Monk has no need to pour it.
