Just to preface: I'm 18.
I went to this show because I was staying at the hotel and wanted to see a show in Vegas that wasn't too expensive and was nearby, so I ended up going to Gordie Brown. Having never heard of him before, I found it incredibly amusing and hilarious. I guarantee I was the youngest person there but I still managed to laugh the whole time and understood 99% of the content. Maybe I'm a bit old school but this guy really strives to please the older audience and everyone in between. It was entertaining the whole time and there were some serious laugh out loud one liners he throws out. (The Neil Diamond and Elton John skits were my favorite).
Go if you're above 30, reconsider if you're below 20, if you know about the Monica Lewinsky scandal and can laugh at George Bush and Obama, you'll have a great time.
