I don't really think it was intentional
But wathcing this for the first time last night since "The Limits of Control," the suit Ghost Dog wears, and then gifts to the ice cream man looks remarkably similar to one of the suits Isaach De Bankolé wears in the new Jarmusch film. Not to mention Ghost Dog leaving his assassin kit with him.
Like I said, I don't really think it was an intentional connection, but fun to think about.
I'm semi-happy... I imagine.
