Quote from Georgie in the episode A Regular Samaritan
Georgie: I feel a little weird. The only time I ever wore this was my dad's funeral. Mandy: Well, I'm sure he'd be glad to know you're getting your money's worth. Georgie: He was thrifty. You know, he's the one who taught me shampoo is really just liquid soap. You can wash your hair with a bar of Irish Spring. Same deal. Mandy: Is that why your hair smells like that? Georgie: Mmm, when you first met me, yeah. Now I'm a Zest man.
