Beer Goggling is now quantifiable

where...

• An = number of units of alcohol consumed
• S = smokiness of the room (graded from 0-10, where 0 clear air; 10 extremely smoky)
• L = luminance of 'person of interest' (candelas per square metre; typically 1 pitch black; 150 as seen in normal room lighting)
• Vo = Snellen visual acuity (6/6 normal; 6/12 just meets driving standard)
• d = distance from 'person of interest' (metres; 0.5 to 3 metres)

I found this at this site which explains why it seems that the fugliest chick in a bar always seems to be more appealing at the end of the night...although it occured to me that the person that would make up an equation like this might get rejected by that beer goggle girl at the end of the night...it works both ways!
