How G-13 escaped the government test facility: The true story.

Working late at night at UofMisss in secret government test labs, I came across this new strain of marijuana called G13. Wow, best plants in the lab. So at great risk I smuggled a cutting home in my sock. Now in order to do this I had to get past the drug sniffing dog. You will never believe it, but it's name was "Rusty". Now Rusty was a vicious, snarling beast of a dog. Quite a few people at the lab enjoyed stirring Rusty up to see him foam at the mouth. I however, had a plan. I would befriend Rusty and escape with my cutting of G13. For weeks I worked on trying to get Rusty to be more friendly, but it was hard work. Finally, I had a plan I thought might work..I brought my female dog to work every day and left her in the parking lot near Rusty's kennel. Sure enough, Rusty fell in love. On a night when she was in heat and Rusty was distracted, I slipped the G13 cutting into my sock. I knew if I got caught the world would never know the joys of G-13. Whew, I made it past the distracted Rusty, sprinted to the parking lot and escaped with my dog. I soon cloned the G13 and spread this lovely plant across the world, leaving Rusty alone and frustrated back at the lab.
