Me and my wingman to be (lets call him Pidgeon) opened a two set in a bar in City X. After some initial conversation Pidgeon decided to tell a story:

Pidgeon: "Would you like to hear something interesting?"

Girls: "Sure :)"

Pidgeon: "Can you guess which percentage of this country's population lives in City X?"

Girls: "About 2%?"

Pidgeon: "Quite accurate. It is more like 3%. However - did you know that 16% of the national syphilis cases occure here" - he then procedes to take a very sharp and knowing look at me...

Never before have I seen women pack so fast ...

As written in a previous post, I lost both my time tested wingmen to relationships. However, due to the fact that both were very good and long term friends, I somewhow never gave thought to what actually constitutes a great wing.
