O Brave New World...

There is an entire version of Humpty Dumpty that I heard recited in a bar once that began: "Un petit d'un petit, a degrées de folles..." or something similar. And the best French professor I had at Northwestern (himself the best sort of example of a non-native speaker who had by dint of sheer will made himself awesomely fluent, and him with a Pittsburgh accent) used to challenge us to create sentences that worked grammatically but sounded like English with a heavy (an 'eavy) French accent.
