How NOT to video comment

Should I be taking this seriously? 

The other day I posted a question to about possible pitfalls of duplicate content as  it pertains to Search Engine Rankings (SEO). 

That's important stuff to bloggers.  Do a search Mike and Mortgage on Google and I'm going to be right at the top. 

• How many Mike's are there in the world? 
• How many Mortgage companies, web sites, individual pages? 

Currently I'll show up as #3 out of 12 Million.  That's why Page Rank discussion is high on the list.

But back to the point. 

So I posted my question, got some answers, and somehow got this guy.

He's French, living in Paris, doesn't understand English, but somehow felt compelled to comment.

Not only did he comment, but didn't he just release an "under leg noise?"

 

Should I be offended?  

Should I laugh it off?  

or should I comment back? (if you know what I mean)
