[CentOS] httpd log weirdness

Hi All,

I setup a new Centos 5.5 bod and it will be running a site for me. Apache is running and daily I get e-mailed a log from the box. 

The log today said:

--------------------- httpd Begin ------------------------ 
Requests with error response codes
   404 Not Found
      http://www.cablecarmuseum.org/Car42.jpg: 1 Time(s)
---------------------- httpd End ------------------------- 

But that is not my domain at all. How would this entry show up in my log?

I ping'd the domain above and it does not resolve to the IP of the box or any of my IP's.

Can anyone shed some light on this?

Best,
-Jason
