Anything with GSP is worth going to.
Quick story - I was in Vegas like 5 years ago at the Hard Rock drunk out of my mind and with my roommate who was a huge UFC fan. We were talking to this rather short Canadian dude with an accent and having a good old time bullshitting and what not. Dude buys us a round, we return the favor and he hugs us and takes off. My roommate looks at me and goes "Goddamn, that GSP is a nice ass dude." I'm like "THAT WAS GSP?!? WHAT?!? HOLY SHIT." Oops.
