What is it with some people's fetish to show their bluff?

I was playing a SNG on Stars and two jackasses would show their hands EVERY SINGLE TIME that they bluffed. What do they want, a medal? We all do it all the time. So what! You took down 45 chips in blinds. Congrats. Don't spend them all in one place. That also touches on another thing. What in the world would make you want to take the blinds in the FIRST ROUND. If you've got a hand raise, but why take the chance with 34 if your getting 20 chips. Needless to say, these guys were out before the third round of blinds. I just don't get some people. Sorry about the rant.
