Luis is a Hispanic day laborer whom Stewie picks up in "American Gigg-olo" in an effort to get Brian fired from Mega Hardware.

When Brian becomes insufferable after adopting a blue collar attitude when he gets a job at the hardware store, Stewie offers three day laborers $20 to come with him so he can pick their brains. However, he finds out that their ideas are primarily limited to getting him deported or killing him.
