Once in my algebra class, I was near the brink of sleeping (as usual), but my teacher took notice. He asked me a question: "what is 8 x 8?" It was part of a step in solving an equation. I didn't hear his question correctly, as I was a sleepy head. The student behind me whispered 37, and I quickly blurted out, "37." Laughter ensued. I drowned in my own embarrassment.
