Supernatural is on Thursdays, which is the strongest evidence as to why it's the greatest day of the week. (Of course, I haven't taken Evidence yet, so that isn't "official" or anything.) It also falls perfectly in the week where I can look forward to this one day and then be treated by the weekend immediately following.

Thursdays are actually my busiest day with class and teaching. I barely have time in between the classes I'm taking to rush to the class that I teach and then back to the law college for the rest of the day. *Whew* I don't wake up on Thursdays and agonize over how loooong it is until I can watch Supernatural (that, is actually reserved for Wednesdays). What happens is that I wake up and think "Hooray! Supernatural!" Then, the rest of the day speeds by, and I'm only BRIEFLY tempted to talk about Supernatural during the class I teach (whereas, on Tuesday, I consider how I can incorporate it for the entire hour and 15 minutes - I must be the worst TA of all time).

Eehh.. I'm only writing this to pump myself up for tomorrow because today is only WEDNESDAY!! ARGH! As noted above, Wednesday sucks, as a matter of law.

To put my week in perspective:
Monday - School. Waste time on the Internet. Stay up until 3 a.m. preparing for Tuesday.
Tuesday - School. Teach. Consider bringing up Supernatural to my students in a completely casual way. Stay up until 1 a.m. doing homework.
Wednesday - Wake up and for a small moment think it's Thursday. Agonize over the fact that it is NOT Thursday. More School. Stay up until 3 a.m. preparing for Thursday.
Thursday - Hooray! School. Teach. Hooray! Supernatural. Smallville. Consider rewatching Supernatural. Homework. End up staying up until 3 a.m. doing homework (thanks in large part to general watching and sqeeing).
Friday - School. Watch Supernatural. Twice. Homework, but only until 7 p.m. 

In about a month, my weekends will be as action-packed (err.. homework-filled, anyway) as the rest of the week.  Thursdays will no doubt become even more fabulous at that time.
