Well ... I did use "Whoever he is, I'm jealous !" once. It raised a smile and a laugh, but as I said it when I met her to go out for a drink I can't say it worked as a chat up line (and she did look very good too)..
A man once licked my back as I was standing at a bar. When I asked why he said he heard girls liked that. I asked how he'd like it if I flobbed down his back. He said fair point and left. He was minging, had he been hot he may have pulled it off :o)
I had a
'your eyes are like spanners...everytime you look at me my nuts tighten!'
I laughed which i don't think was the response he wanted!.. he was actually using this as a serious pick up line!! x
