Best Compliment Ever

Last week I did an exercise where I teach students that correlation doesn't equal causation.  For example, just because crime rates and ice cream sales go up in the summer doesn't mean ice cream causes crime.  Both things increase as a function of the weather.  Now I feel like I am composing something for one of my classes so let me get to the good part.....the next class period a student tells me that he had to go home and tell his buddy about the lecture and then says: Man, you blew my mind.

Best. Compliment. Ever.
