Disguise - The funny Story
He told his friend that he's gonna disguise himself as the professor and will pull HER leg.
Next day, he came to college as the professor and went to her.... SHE stared at him and hit him with a tight slap, before he could say anything she kissed him very gently on his other cheek.
He cheeks were so red that one may think of a sun burn but he was blushing.
PS - he still doesn't have a clue his friend sold him out
