Two fellows have been at the bar now for quite a while, downing several mugs with abandon. They both look at the far end of the bar, in the direction of an unattractive woman who came in a while back.
The first fellow looks back at the second fellow and says, "Ya know, that woman is looking better and better, isn't she?"
The second fellow takes another look at the woman, then looks back at his friend and says, "well, I guess what they say is true, then, eh?"
The first fellow asks, "Well, what DO they say?" The second fellow answers, "Beauty is in the eye of the beer-holder!"
