You know, taking a shill friend would be perfect for meeting girls at the bar. You could go to the can, and they would go on about how great you are, about the Ferrari's you own, the island in the mediterranean where you work with orphaned dolphins, and so on. You then come back and act bashfull if the girl asks about any of the tall tales. "I don't like to talk about me, lets talk about you..."
When it all comes out later, after she wakes up in your double wide down by the railroad tracks, you act all shocked: "What did he say?! What a flakey guy, always making up stories..."
Brilliant.
