We know that April Fools’ Day was almost a week ago, but a video has emerged of perhaps the day’s best prank.

Without giving away too much, it takes place in a macroeconomics classroom in Grand Rapids, Michigan, in the US.

The Aquinas College professor has one rule: If your mobile phone rings during his class then you must answer the call on speaker phone.

Let’s just say that this rule might have come back to haunt him somewhat.


Enjoy.
