People I work with are always amused by my excessive use of "foo" in naming things while I do examples or sketch out ideas. I was equally amused with Hanselminutes 55 which I can roughly quote here:
... so once you've got your foo class accepting a bar class
and more likely it's going to be accepting a IBar interface... foo depends on bar which depends on blah and yada ... your instantiation looks like new foo, new bar which takes new yada...
The conversants, besides Scott were Aaron Jensen and Jacob Lewallen.
