National Pizza Expo is happening this week in Vegas. (seriously)
And, if I'm not mistaken, the national porn star convention is also held in Vegas this week. It's not a coincidence that a bunch of the guys from the pizza shop are going to Vegas (leaving tonight or tomorrow, I believe)
If you do make it to Vegas, go to the porn convention... it'll be the best $20 you've ever spent. (judging from the pictures coworkers brought back last year)
