After a wedding in ancient Babylonia, the bride's father would supply his son-in-law with all the mead -- an alcoholic beverage made from honey -- he could drink in a month. This period was called the "honey month," which became known as the "honeymoon."

Before thermometers were invented, brewers would dip a thumb or finger into the mix to find the right temperature for adding yeast. Too cold, and the yeast wouldn't grow. Too hot, and the yeast would die. Thus the phrase "rule of thumb."

In English pubs, ale is ordered by pints and quarts. So in old England, when customers got unruly, the bartender would yell at them to mind their own pints and quarts and settle down. It's where we get the phrase "mind your P's and Q's."

Before the discovery of fish, in ancient Japan, all they had to eat were those stupid blocks of pressed tofu. Of course, eating utensils had not yet been invented, so people had to swallow them whole. This gave rise to the expression "a square meal."

This Week's Contest was suggested by Kevin Cuddihy of Fairfax, who wins a CD containing 10 songs for dogs, including "If I Only Had a Thumb." Kevin sent us the above etymologies, all beer-related and all allegedly true, as compiled by Pete's Wicked Ale. Your challenge this week is to make up similar historical explanations -- they should be vaguely plausible, not necessarily beer-related -- for the etymology of any term you wish. The term should be the punch line. First-prize winner gets an unopened bottle of vintage Elvis Presley "Love Me Tender" moisturizing milk bath. It smells astonishing, like a puree of Kaopectate, apricot liqueur and 20 Mule Team Borax.
