All I can say, AgentM is you must go to very different places to meet members of the opposite sex. I tried a similar line to yours:

• as a pickup line ("Did I mention I'm a perlmonk?" -"Your place or mine, hotcakes!")

and the responses were:

• three women gave me strange looks and moved to the other side of the bar;
• two women threw their drinks in my face;
• one called security and two HUGE bouncers threw me out into the street; and:
• one woman started some strange chanting - and I moved to the other side of the bar.

What is your secret? (hotcakes????)
