Lactose Intolerance Special Case

My right nose is Dutch Lady Strawberry lactose intolerant.

Why right nose? Because my left nose is just fine.

Why Dutch Lady? Because it never occurred with Marigold.

Why Strawberry? Because it never occurred with Chocolate.

Why lactose? Because it's milk, goddamnit!

Why intolerant? Because my right nose has been running for two days, non-stop. Someone help me catch him!
