CHICAGO - In a cruel twist on the tradition of forcing rookies to sing in front of their teammates, Chicago Cubs veterans have forced their rookies to listen to a Katy Perry song, twice, with the volume turned up all the way. Rookie Addison Russell recounted the harrowing experience on Monday. “Whew, that was a tough one,” he said. “I’ve been hazed before but usually it just involves putting on a dress and singing something stupid. This? This was a whole different level. They sat us down, put headphones on us, and cranked the music up all the way. I think it was ‘Firework’ or ‘Firecracker’ or some other piece of crap. And the way that idiot yell-sings I thought my ear drums were going to explode. Halfway through the second listen I was begging to put on a tutu and sing I’m a little Teapot, but no. These guys are obviously sadists.”
