As someone who has watched a great deal of tennis I have to say the most obnoxious fans I've ever seen (at a tennis match) were the troglodytes at today's French Open at the Fritz v Rinderknech match. I've seen a lot of bad sportsmanship but these Philistines sunk to the level of the sewer today. #frenchOpen #Fritz #RolandGarros #MoronicFans
