Planking, Tebowing and Eastwooding

First there was planking. Then there was Tebowing. Now, it appears Internet users have found something to fill the photo meme void: Eastwooding.

Clint Eastwood received a lot of online buzz Thursday night after pulling an unusual stunt at the Republican National Convention: talking to a chair with "Invisible Obama" sitting in it.

Eastwood and the chair were a hot topic throughout the evening, even during speeches by Florida senator Marco Rubio and GOP presidential candidate Mitt Romney. It started as a macro image meme, which users photoshopped and added comical captions to the image of Eastwood and the chair.

The conversation was fueled by the POTUS himself when Barack Obama's Twitter account sent an image with a strong message: "Seat's taken."

Now, Eastwooding has become a photo challenge. Similar to planking, Internet users are uploading photos of empty chairs with the hashtag #Eastwooding. There are already hundreds of images on Instagram, Tumblr and Twitter.

Will Eastwooding last as long as planking and Tebowing? Which was the best? Let us know in the comments below.
