It’s Monday and most are back to a full week of work, so here is a good laugh to get you started for the week.

Here, we take a look at this hidden camera show where some judo practitioners were partnered up with a new student in the class.

Things take a wild and crazy turn when the instructor pairs one of the judokas up with the new student for some sparring. After the two students bow to each other in respect, the two take their fighting stance. This is when the new “student” decides to take her gi top off exposing her bare upper half as part of the prank on the judo practitioners.

Take a look and have a good laugh at the hilarious reactions from the students being pranked as some of them run away from the topless judo fighter while covering their eyes and one goes as far as climbing up some gym equipment to avoid the situation. The woman eventually tells the students that there is a hidden camera and everyone can’t help but to break down in laughter.
