One of Tony's cellmates turns out to be a draft dodger called Fred the Professor (Austin Pendleton), an electronics wizard who has renounced technology, but makes an exception in rigging a television set to allow Banks the opportunity of cell-to-cell communication with Packard. Banks realizes he can't kill his old friend, and, as a result, will probably never leave the prison. He writes his wife with the news, on stationery borrowed from Fred, while ignoring Fred's admonition not to lick the envelope and discovering the hard way that all the stationery is soaked with LSD... enough to send the whole prison on a bad trip. One of the inmates, Leech (Michael Constantine) says, "Hey, maybe if I take some of that stuff, I wouldn't have to rape anybody anymore." Fred guides Tony through the resulting acid experience, helping him come to terms with his worries about Darlene and his past while plotting their escape.
