In a series of three videos, Crosby and MacKinnon pick up a large order of coffee and other beverages, crash a street hockey game and pay a visit to a fire station.
Last year, the pair took a turn as Tim Hortons drive-thru employees to the surprise of the store's customers.
In the first of the latest videos, Crosby struggles to navigate the large Tim Hortons van, while MacKinnon does most of the heavy lifting.

When they pull up to their destination, Halifax Regional Fire & Emergency - Station #3, one firefighter has a hilarious reaction. Soon, the two are doing firefighter drills and MacKinnon realizes he's not cut out for the job, if for no other reason than his fear of heights.
