Who was Puck? Give three examples of his pranks.

Puck who is also known as Robin Goodfellow is a fairy whose master is the fairy king Oberon. He first appears in Act II Sc. 1 when he discusses with Titania's fairy the quarrel between Oberon and Titania. It is from their conversation we learn of the mischievous pranks of Puck. Three of his pranks are:

1. "Mislead night-wanderers, laughing at their harm." Puck would deliberately mislead  the travelers and make them lose their way in the dark night.

2. "sometime lurk I in a gossip's bowl,

In very likeness of a roasted crab,
And when she drinks, against her lips I bob
And on her wither'd dewlap pour the ale."

Sometimes Puck would take the shape of a crab apple which an old middle aged lady would take along with her ale, and then just as she raised the drink to her lips Puck would rise to the surface of the cup and shock and surprise her, and the frightened lady would pour all the ale over chin.

3. "The wisest aunt, telling the saddest tale,

Sometime for three-foot stool mistaketh me;
Then slip I from her bum, down topples she,
And 'tailor' cries, and falls into a cough;
And then the whole quire hold their hips and laugh,
And waxen in their mirth and neeze and swear
A merrier hour was never wasted there."

Sometimes Puck would take the shape of a three legged stool and fool a solemn lady  to sit on himself  while she was narrating a sad story to a group of people. Then at an important point in the story he would slip out from her bottom and she would fall down and swear and curse to every one's delight.
