A group of students had some fun at their teacher's expense in a very funny April Fools prank.

Apparently the teacher has a very strict rule about no phones in class and the students decided to have some fun with the rule.

Amazingly, everyone, including the teacher enjoyed the joke and no one got suspended or sent to the principal's office! It's nice to see that students and teachers can still have some fun every so often. Watch the video above.
