Title: Still Crazy Movie plot: "History teaches us that men behave wisely . . . once they've exhausted all other alternatives. For most rock bands, the pursuit of wisdom's a low priority compared to fame, fortune and fornication. Such a band was Strange Fruit." Thus begins the opening dialog of Hughie, (Billy Connolly) as he launches into a brief history of the British band: in the late 1970's Strange Fruit, consisting of guitarist Brian Lovell (Bruce Robinson), his brother and lead singer Keith, keyboard player Tony Costello (Stephen Rea), bassist Les Wickes (Jimmy Nail) and drummer Beano Baggot (Timothy Spall) were HUGE. When Keith died of a drug overdose, he was replaced on vocals by Ray Simms (Bill Nighy). Watched over by road-dog Hughie and Girl Friday Karen (Juliet Aubrey), they soldiered on until the disastrous appearance at the open-air Wisbech (U.K.) Rock Festival, when lightning struck the stage during their opening number. The already-contentious band members decided it was a sign and immediately broke up forever (all this in the first five minutes of the film). Forever, that is, until in the present (OK, 1998) Tony is spotted on Ibeza (he now stocks condoms in the restrooms at the resorts there) by the son of the Wisbech promoter, who wants to put together a 20th anniversary reunion concert with all the original acts. Tony seeks out Karen, now a divorced mother who coordinates conferences for a major hotel, suggesting a possible reunion. She is ambivalent, as is Les (now a successful roofer with a family) and Ray (a struggling solo artist with a demanding second wife -- Swedish -- and a mansion he can't afford). Beano, working in a floral nursery and hounded by the Inland Revenue (the U.K.'s IRS) is the only immediately enthusiastic bandmate. They arrange a meeting, where Karen informs them that she's tracked Brian and found his music royalties are being distributed per a bequest in his will, provoking Beano to compassionately ask if that means "the silly sod's dead?" The band again soldiers on. Hughie shows up to complete...???

Problem: Given the question: Extract the answer to the following question from the movie plot. If the question isn't answerable, please output "Can't answer". Question: What rule do the prisoners must obey Title: Das Experiment Movie plot: While reading a newspaper advertisement, taxi driver Tarek Fahd discovers an invitation to participate in an experiment, in which 4000 German marks are offered to the participants of the experiment, in which a prison situation is simulated. The experiment is led by Professor Klaus Thon and his assistant, Dr. Jutta Grimm. He decides to join in. Tarek participates as a journalist while wearing a pair of glasses with a built-in mini-camera. Tarek has a car accident shortly before the experiment, after which he meets a woman called Dora. She spends the night with him and Tarek keeps thinking of her, shown in flashbacks. The 20 volunteers are pronounced guards and prisoners, 12 prisoners and 8 guards, and are being observed by a team of scientists. In the experiment, the prisoners lose their civil rights and have to obey arbitrary rules, such as completely eating their meals. The guards are given nightsticks, but are told not to use violence in any case. Each prisoner's name is taken away and replaced by a number. Tarek (prisoner nr. 77) initially refuses to acknowledge the guards' superiority by drinking the milk of one of his co-prisoners because of that prisoner's lactose intolerance, or by throwing his blanket out of his cell to provoke the guards. He befriends his cellmates, Steinhoff and Schutte. Psychological changes develop and the situation deteriorates. The circumstances seem to be escalating after a few days. It becomes clear that limits are not only being reached but being surpassed when the guards kidnap Tarek from his cell late in the night, order him to strip fully naked, shave his head bald and urinate on him. The guards become excessively aware of their power and use the prisoners' fear to make them obedient. On both sides, one person is considered dominant. On the prisoners' side, this is Tarek, and on the guards' side, it is the quiet guard Berus, a sadist, whose motto during the experiment is: "Humiliation is the only way we can solve these troubles." From that moment on, the guards start...
