He's obviously being funny, guys.
Referencing an old anecdote: "A Soviet and an American nuclear submarine meet at sea. Out of the properly maintained US submarine climbs out a groomed captain, out of the Soviet rustbucket climbs out a bearded and filthy captain, yelling: "WHO THREW HIS BOOT ON THE CONTROL PANEL? WHO THE HELL THREW HIS BOOT ON THE CONTROL PANEL?" The American captain then speaks up: "You know, we in the America..". The Soviet captain interrupts: "Your beloved America doesn't exist anymore, WHO THE F%! THREW HIS BOOT ON THE CONTROL PANEL?".
