Definitely odd. I just like'd a page on your site. The Like comes through on FB properly and the link *looks* correct. However, there's obviously a redirect happening there to Google. From a quick check of how the redirections are happening, I hate to tell you, but it looks like you may have some malware or something else odd going on on your server. First, the screen capture of what's happening:
From that image, you can see the redirect to the 816-rate-card-ology.. page from your site. That page is then redirecting to homepageactionwise . ru . I don't know what that site is, I haven't visited it, and I don't plan on it. My guess is that it's a malicious site, but maybe you know what it is.
Anyways, once the redirect goes to that site, it then redirects again to Google. My guess, though I couldn't see it in there, was that there is some sort of tracking or referral code being set so that there is some commission or other kickback from searches going to the homepageactionwise site. Again, this latter part is all a guess, but something seems to be detecting requests that are coming from Facebook and redirecting those to the homepageactionwise site and then to Google. The homepageactionwise site may check for certain browsers/OS's and then install 'bad' stuff if it finds the right combo. I just can't tell.
Hope that helps explain, though I'm sure it's now what you want to hear. If you don't know what that site is and have no affiliation with it, you may need to check your site/server for security issues and or contact your host to help you with that.
