TSQL : Revealing Foreign Key Constraints

Back in the day I blogged on revealing Referential Integrity via Information_Schema views. Here is an updated script to do the same.
    ForeignKeyName   =
   ,TableName   = OBJECT_NAME(fk.parent_object_id)  
   ,ColumnName   = COL_NAME(fkc.parent_object_id, fkc.parent_column_id)
   ,ReferencesTable  = OBJECT_NAME (fk.referenced_object_id)
   ,ReferencesColumn = COL_NAME(fkc.referenced_object_id, fkc.referenced_column_id) 
FROM sys.foreign_keys fk
INNER JOIN sys.foreign_key_columns fkc 
   ON fk.object_id = fkc.constraint_object_id
