Say what you will about Metallica (I’m prone to superlatives, personally), but those dudes have a pretty good sense of humor about themselves (check Lars’ cameo in Get Him To The Greek for evidence of this). Now they’re doing a new promo for SportsCenter, built around the conceit that following Mariano Rivera’s retirement, the ‘Tallica dudes have been hanging around ESPN HQ in Bristol, Connecticut, trying to find work. It’s pretty funny, and you should watch.
