Arsole? Putrescine? Dickite? Moronic Acid? This list of Molecules with Silly or Unusual Names (one NSFW image) proves that scientists can be funny, as does this Stuffy Scientists page, and Mark Isaak's terribly thorough Curiosities of Biological Nomenclature (see, especially, Puns). If you are tempted to wonder what the Father of Taxonomy might have thought of the irreverence of those last two collections, keep in mind that Linnaeus himself named this plant "Clitoria Mariana" in honor of an 'acquaintance', according to this page.
Pick your poison: highbrow (virtual tour of 10 Downing Street), or lowbrow (virtual tour of the White House). Hint: one of these is funny.
