Transcript for ABBA Celebrates 40th Anniversary of Breakthrough Performance

Meet max, who may just be the most of them all. He sees an open box, he runs for it. Already getting more than 73,000 clicks. He's wearing it? He's wearing it. You have some competition for the craziest cat out there. And this kitty is on your radar. You can never go wrong with skimbles. Just genius, gio. "Dancing with the stars"
