Question: The actor who starred as Buck Dharma in the "More Cowbell" sketch on Saturday Night Live was born in what year?

full_context: Document 1: The Chris Farley Show: The Chris Farley Show was a sketch from the American comedy TV series "Saturday Night Live", which involved comic actor Chris Farley, as a parody of himself, interviewing various celebrities. Rather than ask his guest questions that had any popular significance, or allow his guest to plug a current project, he would invariably act nervously, and simply describe scenes from a film in which the guest actor appeared (or occasionally films that had nothing to do with the guest). After asking the performer whether he remembered this particular event, Farley would relate, "That was awesome." Other times, he would ask questions that were of little relevance, or made no sense at all. Invariably, he would say something he regretted and would smack his head and call himself an idiot. The skit accentuated Farley's shyness for comic effect.
