Hey now don't get carried away... didn't you know that the fly on the wall in his office carried a tracking device which he safely placed in Leo's carryon (because he doesn't like long trips and preferred to stay behind and read his Mail)

Monitoring from Leo's office Mr. Fly has been keeping notes on his movements which should soon be reported in the Journal of Medicine and available when you pledge a contribution on Kickstarter for his patent pending Fly Eye binoculars.
