Grover has a way of trying to escape the house through the front door (though I don't know what he would do if he got outside). I laugh every time.
sorry the video is sideways, I don't know how to fix it.
I swear he will do this for 15 minutes. But each time I pick up my camera to catch it, he stops. I wonder if he actually thinks he will be able to get out through the window.
