Table schema:
CREATE TABLE table_name_1 (co_driver VARCHAR, number VARCHAR, position VARCHAR, year VARCHAR, laps VARCHAR)

Question: Can you tell me the Co-driver that has the Year smaller than 2012, and the Laps smaller than 161, and the Position of dnf, and the Number 33?
SQL: SELECT co_driver FROM table_name_1 WHERE year < 2012 AND laps < 161 AND position = "dnf" AND number = 33
