Amateur radio operators are not all serious business; some of us actually have a sense of Yuma (and fondness for puns). It may be obscure and occasionally off-color, but some of it is pretty funny.
You can find bits of amateur radio-related humor on various ham websites.
For our part we have created a new Ham Humor page here which contains links and a selection of favorite clean ham radio humor which will grow as new material is discovered. You can always access this page from the NewHams.info site menu just below the top banner.
