I found this story on Baseball Almanac and had to share it. It gave me a bit of a chuckle...
"One day at Dodger Stadium, St. Louis Cardinal catcher Gene Oliver blasted a long homerun off Drysdale. Before beginning a leisurely trot around the bases, Oliver first stood at home plate admiring the flight of the ball and then said, loud enough for Drysdale to hear, 'Hey, batboy, come get the bat.'... The next time Oliver batted, Drysdale drilled him with a fastball. While Oliver writhed in the dirt of the batter's box and teammates and the Cardinals' trainer rushed to his aid, Drysdale said loud enough for everyone to hear, 'Hey, batboy, come get Oliver.'" - Author Mike Shannon in Tales from the Dugout: The Greatest True Baseball Stories Ever Told (Mike Shannon, McGraw-Hill Publishers, 01/11/1998, Page 62)
[edit] While a funny story, I looked up on Baseball Reference for the two occasions that Gene Oliver hit a homerun off of Don Drysdale, and neither one indicated that Oliver was HBP in the same game.
Gene Oliver had 93 career home runs. Guess who he hit 4 of those homeruns off of? None other than Sandy Koufax.
