4x14 - Bob's Burgers

When Bob and Linda leave town for a romantic getaway (at a Burger Convention), they ask Teddy to babysit Tina, Gene and Louise. While the 'rents are away, Teddy is eager to earn the coveted title of "Uncle Teddy" and does so by putting Tina's crush in his rightful place after discovering that he was just using her for – gasp – free burgers! Hijinks ensue.
