You, you mongrel!

You mangy mongrel!

But if you prefer to placate that bloodthirsty mongrel of yours, then kill them.

I hate living in the woods like an animal... people spitting at me and treating me like a mongrel.

Oh, probably thanked heaven there was no one around to fill her house with mongrel puppies and track mud on her carpets.

Mongrel was generally preferred over WEBrick in the early days, but it can also run on Lighttpd, Apache, Cherokee, Hiawatha, nginx (either as a module Phusion Passenger for example or via CGI, FastCGI or mod_ruby), and many others.
