Someone who, at school, volunteers to do an example on the board. Upon reaching the board, the student forgets how to solve the problem and freezes. In a confused and embarrased state, the student then makes his way back to his desk and is shamed by his fellow classmates.
Jon: "I'm done professor"
Professor: "then go ahead and do the sorting algorithm Jonathan"
*Jon draws a blank at the front of the class and returns to his desk shamefully*
