Why is this very simple cursor breaking SQL Server Management Studio?

I have created an item on the Degree table and I want to duplicate that record for 19 other Colleges. I have a really simple cursor, but every time I run it it totally crashes SQL Server Management Studio. Is there a way to rewrite this query (or another query entirely which performs the same INSERT INTO) so that it does not crash (and actually executes)?

DECLARE @Colleges VARCHAR(200)

DECLARE DUPLICATE_DEGREE CURSOR FOR
SELECT CollegeID FROM Colleges WHERE CollegeName <> 'Main Office'
OPEN DUPLICATE_DEGREE 
FETCH NEXT FROM DUPLICATE_DEGREE INTO @Colleges

WHILE @@FETCH_STATUS = 0
BEGIN

INSERT INTO Degree
(
  DegreeName
, CollegeID
)
SELECT
  DegreeName
, @Colleges
FROM Degrees
WHERE DegreeID = 123

END

CLOSE DUPLICATE_DEGREE 
DEALLOCATE DUPLICATE_DEGREE
