a voyage to lilliput mentioned many funny situation describe some of them

Most of what people would actually call funny is rather gross or freakish, that's probably where they find the humor.

"When Gulliver awakens, he is lying on his back. He finds himself unable to sit up or move at all. His "Arms and Legs were strongly fastened on each side to the Ground; and [his] Hair, which was long and thick, tied down in the same manner." He feels something moving along his body almost up to his chin, at which point he sees that it is "a human Creature not six Inches high, with a Bow and Arrow in his Hands, and a Quiver at his Back."

He gives a detailed description of his need to relieve himself after two days without defecating-and how he finally does so, first in his house because of embarrassment and on every following day early in the morning so that it can be carried away by two workers before the general population is awake.

The emperor decides to entertain Gulliver by showing him a tradition of the court in which candidates for an open position of honor compete by walking to the middle of a string or tight-rope that is suspended two-and-a-half feet above the ground. They jump as high as they are able. "Whoever jumps the highest without falling succeeds in the Office." Gulliver tells the reader that very often these competitors are injured or fall to their death."
