In my public speaking class we have discussed: "skullets," bestiality, motorboating (not the kind involving water), homosexuality (one student asked a lesbian in class "how can you knock the wee wee before you've tried it?" << not mean-spiritedly, btw), abortion, our teacher telling us he hasn't dropped acid in 27 years, poisonous spiders, inception, how a woman was married to the eiffel tower, whether Adam named all the animals in one day or not in the Bible. And those aren't the speeches.
God I love this class.
