Check out MacRuby, which is Ruby implemented on top of the Objective-C runtime: http://www.macruby.org/
The key difference between this and other "bridges" is Ruby classes are implemented as Objective-C classes. This couldn't have been done if Objective-C weren't as dynamic as it is. Objective-C is basically Ruby in C's clothing (which leads to a very different "feel", but in terms of "dynamicism" they're approximately the same).
And "slapping it on top of assembly language"? I'm not sure what that has to do with anything. C compilers are usually written in C. V8 (Chrome's JavaScript engine) generates machine code. What exactly is your argument?
