I had a more complicated joke for this one, but I have been leaning toward the wordy side lately and I figured I would go back to simple basics.

The only tricky technical desision was about bolding in his last balloon.  I considered bolding “unaware” and then “France” and discarded them both, because it would disrupt the subtlety.  This joke may not work at all (I can never really tell until I get feedback), but if it does, it’s going to work only by flying in under the reader’s radar.
