Some examples of hilarious poems include Williams Shakespeare's Sonnet #130, "My Mistress' Eyes Are Nothing Like the Sun," "House Cleaning Blues" by Ellen Bailey, "An Actor's Revenge" by Richard John Scarr and "Early to Bed" by Mary Mapes Dodge. Humor in poems is achieved with structure and content.
Poems about pets and animals are often rife with humor. Francesco Marciuliano has published a collection of poems on both dogs and cats. From the poems on dogs, a hilarious example is the short poem "Another Bag." The poem "I Could Pee on This" from the collection about cats is a funny poem that provides insight into the feline mind.
