It's often surprising, even amusing, when unlikely words turn out to be related etymologically, such as vanilla and vagina (pod, sheath). Some of those here seem so unlikely you're unlikely to believe me and will wan to look them up yourself for confirmation or details. Admittedly many pairings are of composite words that share a common root in only part of the word(s). But the two halves of the hyphenated words listed here count separately.
