Dan hears noises downstairs which turns out to be the pledges of DZO breaking in. Because of this little prank, George decides that the pledges have to complete a mission to get back at the girls before the next line-up. He is requiring them to steal the DZO banner hanging in the Student Union, and have all the DZO pledges sign a T-shirt. The guys are able to accomplish the first part right away as Tim steals the banner while the DZO girls are in the building. However, the guys run into problems getting the T-shirt signed.
Later that night, Tim has the idea to create a decoy banner. Good idea, poor execution, and the plan flops. With time running short, they decide to give in to the sisters of DZO who had asked them to write a letter of apology. Dan and Paul deliver the letter to the girls and as retribution the DZO sisters decide to have everyone come to their house to get the shirt signed. However a problem arises when one of the DZO pledges has an asthma attack and the shirt signing takes a backseat.
Because of the problem, the SCO pledges decide to strike up a contract with DZO. They will clean their house if the girls sign the shirt. But in true "boys will be boys" fashion, the guys pretend to be cleaning while really they’re stealing as much stuff from the girls’ house as they can: beer, panties, some paddles, toothbrushes, and top it all off, they toss little pepperonis into the girls’ beds. Once they are done wtih the "job," they finally get their signed shirt.
When DZO finds out what the pledges did to them, they fight back by trashing the guys’ house. As the guys return they cannot find the signed T-shirt anywhere and are convinced that the DZO girls took it back when they ransacked the house. Although they want to stop the feuding, the guys decide to get the girls back for good and some of the brothers hit the DZO pledge house porch with eggs and flour.
The brothers decide that the pledges must sign an apology letter stating that they are sorry for the trouble that they caused DZO and they must return everything that they stole and clean their entire house. As Tim and Stephen deliver the signed apology letter, Stephen can’t help but mutter a disrespectful, “bulls---“ under his breath. Looks like the animosity between the two won’t end here.Back at the line-up, the guys are petrified that they are going to get in trouble for having lost the signed T-shirt. Paul tells George that the girls stole it, but Tim saves the day; he pulls up his shirt to reveal he’s wearing the one signed by the DZO pledges. It turns out that Steve and Tim found it earlier in the day while cleaning the DZO house. Final score: SCO = 1 banner, 1 signed T-shirt. DZO = nothing.
