In Serena subforum I noticed they have a great thread packed with funny Serena gifs. Some of them have been frequently used in GM discussions. I think Petra deserves a similar thread. It's also good to have these gifs ready at a single place.
Here's what we have so far (big thanks to Pling and MaryCherry). Please feel free to add more!
There's another one out there somewhere of Petra slamming a ball to the court with her racquet. It bounces up and hits her in the face. It's kind of funny.
“It's not as if everything revolves around me now that I've won Wimbledon for the second time — as if I'll just sit on my ass at home and send someone to do my shopping for me.” — the lovely and humble Petra Kvitová
