Query Help Needed

HI,
I have a table like below

TABLE EMP HAS TWO COLUMNS

FSTNAME ,LASTNAME
TOM HARRY
RAVI SINGH
HARRY TOM
SINGH RAVI
JUDY LINDA

I need a query to remove rows which are repetative i.e IF
(X,Y) appear once than (y,x) should not be present. Hence the desired output is
FSTNAME ,LASTNAME
TOM HARRY
RAVI SINGH
JUDY LINDA

please help/
