What does Gulliver have to do in the court of Luggnagg?

After arriving at the island of Luggnagg, Gulliver discovers that he will not be allowed to leave unless he receives permission from the King. The whole episode is one in which Gulliver debases himself in front of the King and the court in order to receive what he is after. In order to speak to the King, Gulliver must memorize certain flattering expressions and phrases in the native Luggnagg language, such as "May your celestial majesty outlive the sun, eleven moons and a half."
Furthermore, the King makes Gulliver crawl on his stomach, strike his own head seven times, and lick the dust off the ground in front of him. Gulliver finds that this is not special treatment, but pro forma for anyone visiting the King's court. Sometimes extra dust is left on the floor for unpopular petitioners to eat. Occasionally even poison dirt is placed there to assassinate those that the King truly despises. To speak to the king Gulliver uses an interpreter that he has hired for the occasion. Gulliver's performance apparently pleases the King of Luggnagg, who provides him with a home and an allowance for his three-month stay in the kingdom.
