Chuck had just settled into his seat next to the window on the plane when Alex the "DEA agent" sat down in the aisle seat and put his black Labrador Retriever in the middle seat next to Chuck.

Chuck looks very quizzically at the dog and asks why the dog is allowed on the plane.

Alex explained that he is a DEA agent and that the dog is a sniffing dog. His name is Sniffer, and he's the best there is. I'll show you once we get airborne and I put him to work."

The plane takes off, and once it has leveled out, the agent says: "Watch this." He tells Sniffer to "search." Sniffer jumps down, walks along the aisle, and finally sits very purposefully next to a woman for a several seconds. Sniffer then returns to its seat and puts one paw on the agent's arm. The agent says, "Good boy", and he turns to Chuck and says: "That woman is in possession of marijuana, so I'm making a note of her seat number and the authorities will apprehend her when we land."

"Say..that's pretty neat" replies Chuck.

Once again, the agent sends Sniffer to search the aisles. The Lab sniffs about, sits down beside a man for a few seconds, returns to its seat, and this time, he places TWO paws on the agent's arm. The agent says, "Wow. That man is carrying cocaine, so, again, I'm making a note of his seat number for the police."

"I like it!" says Chuck.

The agent then told Sniffer to "search" again. Sniffer walked up and down the aisles for a little while, sat down for a moment, and then came racing back to the agent, jumped into the middle seat and proceeded to take a dump.

Chuck is really grossed and can't figure out why a well-trained dog like Sniffer would act like that, so he asks "What the hell is going on?"

The agent replied, "He found a bomb!"
