re: Do you always correct people when you know they are wrong about something?

If it is obviously a load of crap, I usually can't help but call them out on it.

I had just replaced the transom in my ski boat and was putting the engine back in. My boat wasn't anything to brag about, so I don't know why anyone would be trying to get over on me, and at the time, it wouldn't even float. A guy with a camp next to ours was talking to me while I was putting the drive back on the boat and tells me how his Tahoe deck boat with a V6 will do 60 mph. I didn't belittle the guy, but did question him on how he measured his speed. When he said GPS, I said that his GPS couldn't be accurate. When he continued with it, I asked if it were being dropped from a plane when he checked it. He still thinks I'm a dick, but so be it.

Another time, a guy at work was arguing about an American Chopper bike, the green and black spider bike, with the ghost tank. I made the comment that it looked great and that you could barely see the gas tank hidden in front of the rear wheel. He called me out that the spider web was actually hollowed out tubes, and that it was actually a gas tank. He got pretty pissed and loud when I disagreed with him, but I that was just too stupid to let stand.
