I believe it was the morning after the 1984 NBA Championship, and Dennis Johnson called the home of the most legendary of them all.
The convo went something like this;
Ring Ring.....
Ring Ring.....
Dinah Bird - "Hello?"
DJ - "Hey it's Dennis, is Larry around?"
Dinah Bird - "No sorry he's gone for a run"
DJ - "A run?"
Dinah Bird - "Yeah he said if he was going to win it all again next year, then he had to start now"

That's what been a Celtic is all about.
