Amazon’s plan to make deliveries with drones within four or five years has drawn plenty of skepticism and jokes. Groupon showed its sense of a humor with a funny plan to use catapults for deliveries.

“I heard this ominous whistling in the air like something was coming toward me,” one customer testifies in the video. “I thought maybe it was a flaming bail of hay or a hot cauldron of oil, something like that. But it turns out it was my package from Groupon.”
