Sign up for sections this morning starting at 9 a.m. on Online Course Selection.

Statistics for course enrollment are available on Yale OCI. The most popular course offering sections at Yale this semester is currently Porn in the Morn, where 568 students, including shoppers, are vying for 360 section spots. Introduction to American Politics faces an even bigger shortage — the second-largest course at Yale boasts a mere 72 spots for 514 shoppers. Likewise, Vikings has 425 students currently enrolled — but there is only space in sections for 234 students. Good luck, Elis. Go forth and register.

Audition this weekend to become the new bulldog mascot. Yale Athletics Marketing is holding tryouts Saturday to select a Yale student to serve as the face behind the newly developed bulldog costume. Applicants must be enthusiastic and energetic, as well as “able to communicate non-verbally with fans of all ages.” The new mascot, who will perform at upcoming sports events, will debut at the men’s basketball game against Brown on Jan. 23.

Today is the last chance to sign up for fitness classes at Payne Whitney Gymnasium. Register in the Lanman Center from noon to 3 p.m. Some popular classes, including Boot Camp, Cardio Thai Kickboxing, Zumba and a section of Beginning Golf, are already full.

Swing dancing spontaneously broke out between the two halves of the Yale Bookstore yesterday at about 7:30 p.m. A sign showed that the event was actually an advertising ploy by the Yale Swing & Blues dance group, whose “Swing Bootcamp” runs this weekend.

Be sustainable; close your windows. An e-mail sent to the student body requested Elis not leave doors and windows open for temperature-control purposes. “[The University’s] heating equipment is operating at near capacity,” according to Yale Facilities Operations, and the weather is expected to hit a low of 1 degree tonight — far below the average January low temperature of 22 degrees.

This day in Yale history

1943 The Army, Navy and War Manpower Commission read a statement encouraging students “to continue in College until called and until definite plans are developed,” rather than “drop[ping] out to await call,” since delays in training programs were so common. Several days earlier Yale announced that numerous new spring-semester courses would be targeted to students who expected to be called in the middle of the term.
