cute...you mean it depends on what "is" is, *doesn't* it.

But to your confusion on the difference...

One is "sometimes used as a succinct and vivid representation of an illogical statement" (news to me...never heard the wikipedia version) and mine is a just spoof on somethings I always found challenging in class. Stuff that seemed illogical but which was proved and all that. Probably just me, but I found it funny. That's not really that hard to understand.
