College GameDay took this week’s show to Cambridge, Mass. for one of the oldest (and smartest) rivalries in college football between Harvard and Yale.

As you can imagine, the great minds of the Ivy League put their genius to good use in the form of some hilarious GameDay signs on the set of the popular pregame show.

Meanwhile, in Knoxville, Tenn., SEC Nation made its first ever trip to Rocky Top for the Vols’ showdown with SEC East leader Missouri. The Tennessee fan base did not disappoint with its signs either, most of which focused on quarterback Joshua Dobbs’ eyebrows (or lack thereof).

In case you missed them, here are some of the best signs from the GameDay and SEC Nation sets Saturday morning:

Week 13 Sign 1

The ultimate academic sin.

Week 13 Sign 2

Even the Ivy League chose not to spare Meyer from its GameDay signs.

Week 13 Sign 3

SDS does not condone cheating on standardized tests, but if true Winston definitely went to the right person.

Week 13 Sign 4

Ivy League wordplay for the win.

Week 13 SIgn 5

Wait, then where have all those tuition checks been going?

Week 13 Sign 8

Missouri fans (and your cushy eyebrows) — you’ve been warned.

Week 13 Sign 10

You see, those arrows are pointing to nothing because Dobbs’ eyebrows don’t exist.

Week 13 Sign 11

No word on whether Dobbs has convinced Lil’ Jon to shave off his eyebrows yet.

WARNING: Once seen, the following sign cannot be unseen…

Week 13 Sign 9

We warned you.
