The difference is Fury doesn't take himself so seriously like Wlad...
it would end two ways:
Make friends and take the joke to new levels
Fury knocks the old man out in the street
What Fury should do is agree to fight on the condition that the loser has to give all there earnings to the winner. I'll bet Briggs wouldn't be so confident then haha.
