Hear the 'Most Wimbledon Warning Ever'

Where and when to pop your Champagne is such a Wimbledon problem. For example, someone got the timing wrong over the weekend at the oldest Grand Slam tournament, where the bubbly helps wash down the strawberries and cream, per the AP. "Ladies and gentlemen, please, if you are opening a bottle of Champagne don't do it as the player is about to serve," Australian umpire John Blom announced just after the start of a match on No. 3 Court. Watch the moment here, described as the "most Wimbledon warning ever" by the tournament's official Twitter feed, per the Guardian.

Anastasia Potapova smiled and nodded in approval at the umpire's announcement. The 22nd-seeded player was serving to start her third-round match against teenager Mirra Andreeva. When she tossed the ball in the air, a cork popped and she sent the serve long. She then lost the point on her second serve, and the umpire's warning followed. Champagne is available on the grounds of the All England Club by the glass, half-bottle, and bottle. "Le White Label Sec" goes for 95.10 pounds ($122) for a bottle. However, you can also bring in your own.
