Dogs have such a great attitude.
When people vomit, they slink off and feel sorry for themselves. After we did correlations in class today, I performed my ESP experiment. Besides finally convincing everyone that I'm nuts, it's supposed to illustrate the regression effect. I draw 8 cards, and look at the suits while sending ESP waves into the class. The students are to zero in on the waves, and guess the suits.
