My favorite Keith Foulke moment:
Game 6 of the ALCS, when he blows that scorching 88 MPH heater past Tony Clark.
In old Sox seasons, Clark puts it in the short porch and the Yankees go to the WS.
But I most remember him saying to Varitek, "Gotta make it interesting, right?" (or something along those lines)
Keith Foulke also should have been WS MVP, but that's a different story.
