Buffy: Stay back, or I'll pull a William Burroughs on your leader here.
Born in 1914, William Seward Burroughs was a writer of the Beat generation. His semi-autobiographical stories generally dealt with his homoerotic urges and drug use, his most famous work being Naked Lunch. After fleeing from the law to Mexico for his drug activities, he showed off his marksmanship to some of his friends by doing his "William Tell act". His common-law wife, Joan Vollmer Adams, placed a glass on her head and he killed her with one shot.
