I seriously thought I was going to get frostbite in class today. The room was so cold.

Great class story: In number theory yesterday, the professor emphasised the importance of counting in arithmetic. Then, from the end of class, we have this dialogue:
Girl in class: So can you tell us when the midterms are going to be?
Professor: Oh, after about three weeks.
G: At the end of this week, then?
P: No. . .
G: Oh, so three weeks from the end?
P: No, no, come on, count with me. One, two,. . . Oh.

*Note* For those of you not at the U of C, this is the third week of our quarter.
