When some lucky passengers arrived at a Canadian airport for their flight aboard WestJet Airlines last month, they were greeted by an interactive Santa.

They told Santa what they wanted for Christmas. Seems innocent enough, right? But here's where the unexpected surprise came in. Unbeknownst to the passengers who were now in-flight, the airline dispatched their employees on the ground to Best Buy and other stores to purchase the actual gifts. When the passengers reached their destination city, the presents they had asked Santa for -- everything from underwear to a large flat-screen TV -- started coming around the luggage carousel.

And below, you can watch the blooper reel as well as a behind-the-scenes video from WestJet:
