(Irish Independent) This math 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.
