J. Thyne), the volunteer officer whose bicycle was stolen and crushed by I Need Money, steals and smokes the Ivory plant, leaving the pair without access to Ivory. Silas begins working on a truth serum for his Botany class, using plant extracts. Silas concludes that, if his experiment works, he will earn an A in Botany, and a guarantee of a next semester. His experiment fails numerous times. Before midterms Jamal suggests they go to a graveyard, dig up a "smart dead guy", and smoke his remains which they attempted to do so with John Quincy Adams. Whereas Silas suggests simply that they study hard for a few hours a day while high. They try Silas's plan, but it does not pan out, as they end up failing almost all of their midterm exams. Desperate to stay in Harvard, they try Jamal's plan, but it proves fruitless, as well. Meanwhile, Gerald, who has morphed into a complete stoner, sees Ivory during one of his binges, and, at Ivory's behest, returns the remnants of the Ivory plant to Jamal and Silas. Due to Gerald's abuse of the plant very little remains and Jamal and Silas continue to fail their classes, which pleases Dean Cain. With the last final exam approaching, Jamal and Silas resign themselves to give up. However, Jeffrey reminds Silas of his guarantee of another semester if he can successfully fix his truth serum experiment. Silas ultimately does, having found a solution in which the last of Ivory's leaves could be used to counteract nausea. Nonetheless, because of their low grades, Jamal and Silas do not receive an invitation to the Harvard Alumni party. Dean Cain, clearly thrilled with this result, tells Bart he does not have to worry about the pair showing up or staying in Harvard. However, that changes when Jamie invites them both as her dates, as her father is an alumnus. At the party, Silas makes things a bit more interesting by testing out his truth serum experiment, which proves successful. At Lauren's presentation at the alumni party of Benjamin Franklin's artifacts, she shocks everyone with her discovery: the artifacts turn out to be a bong. Ivory even shows up with Benjamin Franklin to confirm the bong's authenticity. Dean Cain is outraged by this finding, but the Chancellor decides that he has had it with the Dean and fires him. Jamal and Silas are proud
