Sheriff Jack Carter is not the brainiest person in the top-secret government enclave of Eureka (though his daughter Zoe might be), but even so, he gets his share of solutions to the zany science project problems that arise, including bouts with a time-loop wedding (“I Do Over” on 18 Aug 2008), a trip to 1947 (“Founder's Day”), a series-ending anomaly for Jack and Zoe (“Just Another Day” on 16 Jul 2012), and other time anomalies.
