It's time for the annual all-Greek "Undie Run", and the Pan-Hellenic board voted strongly against it. In an effort to change the vote, Casey uses her political savvy to enlist IFC president, Evan, to stage a petition signing.

Additionally, Evan finds out about Calvin and Grant's relationship and helps them keep it a secret from the rest of Omega Chi.
