Watch: This maths teacher impresses students with most genius April Fools prank ever
This maths professor could have pulled off possibly the most entertaining in-class April Fools joke ever.
Matthew Weathers decided to take the opportunity of April 1 silliness to show of his technical skills to his students.
The prankster wrote on the white board "by mistake" and proceeded to Google a "solution" to his error.
A YouTube video featuring Mr Weathers himself pops up and hilarity ensues.
The online professor attempts to use his sleeve, a cat and cleaning fluid to erase the marker - all to no avail.
Finally, it's a Star Wars light sabre that is thrown "threw the screen" to the classroom teacher that saves the day.
"I've done this kind of thing several times," Mr Weathers told independent.ie.
"Readers on Reddit have requested that I do a "behind the scenes" video, so I'll work on that during Easter Vacation and post that in a couple weeks."
For the April Fools prank, the class is suitably impressed; take a look at the genius here.
