Rubbing
bacon... "These two did oftentimes do the two-backed beast together, joyfully rubbing and frotting their
bacon 'gainst one another, in so far, that at last she became great with child of a fair son, and went with him unto the eleventh month; for so long,
yea longer, may a woman carry her great belly, especially when it is some masterpiece of nature, and a person predestinated to the performance, in his due
time, of great exploits."
François Rabelais (c. 1494 - 1553)
"Gargantua and Pantagruel"
