You're out and you meet two ladies - one is stunning to look at but pig-**** stupid, while the other is as plain as day but has a remarkable mind. You must choose which one you will pursue... ...which will it be?
Beautiful and intelligent = Perfect woman Beautiful but thick as pigshit = Meh Average looking and intelligent = Super attractive Average looking and thick as pigshit = Meh Ugly and intelligent = Meh Ugly and thick as pigshit = Kill it before it can breed I can tell what you're thinking - "What an interesting Venn diagram of Erik's mind" - Indeed it is.
Well, if the intelligent woman is average looking, I'll go for her please. (Where can I claim my prize?)
