Gone crazy back soon

It was the dog...
One day an alien space craft lands in a large park.
The alien steps out of his craft and carefully looks around.
He spots a person walking a dog. The dog arches his back, raises his tail and drops a huge log on the grass. Very politely, the person reaches in his pocket and withdrawls a orange plastic sack. The person bends over and using the bag as a glove scoops up Fidos giant steamer. After seeing this, the alien being walks up to the dog and says "Take me to your leader"
