The Princess Lobster fell in love with a crab. They hid this from the King Lobster while they dated.
One day, the King Lobster found out that his daughter was dating the crab and blew his top.
"No child of mine will be seen with a lowly crab! He can't even walk forwards, all he does is walk sideways! You are now confined to the Palace! Now.. it Crab can walk forwards and backwards, I would not stand in your way but we know it's impossible!"
With that, the Princess Lobster was confined and could not meet the crab anymore. But she sent a note to crab through her lady-in-waiting and told him that the King Lobster has confined her and they can never be.
Crab cried bitterly and started to drink to drown his sorrows. In fact, all he did was drink and became a drunkard.
The King Lobster, seeing his daughter also distraught and sad, decided that there are many other royal lobsters in the Seven Seas and threw a gigantic ball and invited all the Blue Lobsters to attend.
Princess Lobster wasn't very happy but protocol insisted she attend so with a glum face, she sat beside her father at the ball.
Suddenly, the door was swung open...
And.. Crab walked in... claw over claw, he walked in.. forwards.. and then.. backwards! As if to taunt King Lobster for his proclamation.
King Lobster looked up... astonished and was about to proclaim Crab was free to see his daughter when Crab uttered..
"Damn.. I am SOOOOO drunk!"
