The Cambodian government became concerned when it noticed young people falling over in Phnom Penh from laughing. They found this most peculiar until they spotted a surge of nitrous oxide balloons floating above a nearby backpacker’s hostel and decided this should stop. Laughing gas is still quite popular as a sedative in Cambodia hospitals (this went over our heads) but then we should allow for cultural differences.
The man in the balloon is laughing because happy pizzas topped with marijuana entered the market since and there’s no law against this in case you’re getting tired of the old familiar flavors. Pot Pizza or Pizza in a Pot?
