Conversation between myself and a cop with a drug-sniffing dog

Cop: Do you have any drugs in the car tonight?
Dog: [starts running around in the backseat]
Jim: Not to the extent of my knowledge.
Cop: When was the last time you took drugs?
Dog: [begins to bark]
Jim: I don't do drugs.
Cop: You haven't even experimented with recreational drugs?
Dog: [runs and barks wildly]
Jim: No... Is your dog getting worked up because it hears you saying, "drugs"?
Cop: No. I wish it were that easy. All of his commands are in Dutch or German. He doesn't speak much English.
