It's okay to have fun, and the photographs that seem to fit into this category are all in that spirit.  Capturing images of a flower that can work together with others reminds me of Warhol's "Soup Cans", and whimsical shots of what seems a monumental grasshopper on the loose simply makes people laugh. "Bread Loaf" leaves people wondering what it could possibly be, mountains in China?  They're usually very amused to discover what it is.
