Clint Eastwood, 82, made headlines at the Republican National Convention when he devoted his speech to debating an empty chair he pretended was occupied by President Barack Obama. Not surprisingly, Twitter blew up on the topic and two Twitter handles were created in response to the spectacle. The first, @Clintschair did not gain a great following, but the second, @InvisibleObama, became an instant hit. @InvisibleObama has been offering mocking tweets and has gained upwards of 42,000 followers and counting.

Of course, the real benefit of Eastwood’s bizarre rant is the witty reactions it inspired on Twitter by celebrities and pundits. The best reaction, though, came from the official Twitter account of President Barack Obama, @BarackObama, who tweeted, “This seat’s taken,” with a picture of himself sitting in the president’s chair. Below are our Top 10 favorite tweets from Eastwood's empty chair rant.
