S5E18: Meet the Quagmires
Hey, where the hell is Lois?
Looks like she's coming out of Quagmire's house.
Lois, what the hell?
I'm gone for one night, and you sleep with Quagmire?
Mr. Griffin, what I do with my husband is none of your business.
Husband? Morning, Pete.
Hope you and Molly can still join us for dinner tonight.
