I laughed much harder at this joke than I should have:
"There once was a stoner that was down on his luck. In order to raise some money he decided to kidnap a child and hold him for ransom.
He walked to a nearby playground, grabbed a kid, took him behind a tree and said to him, "I've kidnapped you."
The stoner wrote a note saying "I've kidnapped your kid. Tomorrow morning put $10,000 in a paper bag and put it beneath the pecan tree next to the slide on the east side of the city playground. Signed, a stoner."
The stoner then pinned the note to the kid's shirt and sent him home to show it to his parents.
The next morning the stoner woke up early and rushed to the playground. Sure enough a paper bag was sitting beneath the pecan tree. The stoner opened up the bag and found $10,000 in cash along with a note which read, "How could one stoner do this to another stoner?"
