Tape yourself at a McDonald's drive-thru (To avoid illegal videotaping inside the restaurant) ordering a McGangBang (By name, not the individual items), then at the cashier's confusion, explain how to construct the sandwich, then show the results of their efforts.
Per Urban Dictionary:
This is a tasty sandwich combination from McDonald's. Off the Dollar Menu you order one double cheeseburger and one Spicy McChicken sandwich. Spit the double cheeseburger between the two patties, and then put the entire Spicy McChicken sandwich inside the double cheeseburger. This originated from Daytona Beach McDonald's Restaurants.
Wait, you ride the bus and walk all the time.. Do you have a car or access to one?
EDIT: You must, you crushed the coconut with a car in the first video...
