They say what happens in Vegas stays in Vegas. But does it really?
Maybe you got married to that really nice stripper when you were blackout drunk. Or maybe you got annihilated at the Bellagio, won $3000 and then blew it all on cocaine and are passed out in a fountain right now. You may not remember everything that happened, but that doesn't mean the crazy sh*t you did (and f*cked and threw up on and passed out near) at your friend's Bachelor party will be forgotten by the the masses on the strip.
So pass the aspirin and stop talking so loud because after a trip to Las Vegas, you're shame might be worse than the devastating hangover you're bound to be nursing for at least the next few days.
