This reminds me of an old joke. A single dad struggling to make a living and bring up his young son to be a respectable human being faced with the inevitabilities of puberty and when confronted with the inevitable curiosity that male adolescence has about the fairer gender he decides to nip in the bud by convincing that women had teeth in their nether regions which would naturally make it a perilous place to insert ones throbbing manhood. The well intended if errant words stuck and the lad grew through his teens more than reluctant to breach the subject of sex to any of his considerable number of dates despite a few being more than willing to be deflowered by him. Well time passes and dating leads to engagement and inevitable betrothal. The son, now a strapping young man and newly married carried his beautiful new bride across the threshold of the honeymoon suite to the unfamiliar territory of the bed where the nubile and newly Mrs. proceeded to disrobe and attempted seducing the young man to consummating the marriage. Naturally the tragically misinformed groom recoiled in terror saying "but you have teeth down there!". Bewildered but amused, the bride removed her panties, laid back and spread her legs, showing the young man her toothless vagina, to which he replied, "wow, there AREN'T any teeth... but your gums look pretty bad"
Yet again, the members of Hip Forums came through for me and provided me with a much-needed laugh, thanks Stinkfoot.
