WATCH: The Williams Sisters Are Forrest Gump Good at Ping-Pong

In a new commercial for the Apple iPhone 5, the Williams sisters prove that it’s not just regular tennis they’re awesome at, they’re pretty good when it comes to the table version too.

The commercial is specifically aimed at promoting the phone’s “Do Not Disturb” function, which allows users to be blocked from calls, emails, texts and Facebook notifications. In what is hilariously ill-timed, this Apple blog posted last night noting how many iPhone 5 owners were complaining that “Do Not Disturb” was malfunctioning.
