the legend of DOLLAR FIFTY GARCIA

In 1972 or so, Gene Freeman would confidently stroll into class every day and walk right past Gary Garcia.
Gene always said the same thing to Gary Garcia..."DOLLAR FIFTY GARCIA..."
Gary would never respond...
Why did Gene say these words to Gary?
Did Gary owe Gene a Dollar Fifty?
Why did Gene loan Gary a Dollar Fifty?
Did Gene sell something to Gary for a Dollar Fifty?

This mystery has plagued me and several friends for years!!!!
