No one has ever tried a "chat up line" on me!
My usual chat up line is "Hello". And the usual response is "F*ck off!" (I've tried everything to date and my lines still don't work. Next up - plastic surgery and personality transplant!)
Mind you, my fortunes have changed since joining E-I. Nowadays my chat up line (with the ladies here of course) is " Are you free for an hour?" Works a charm everytime. Have not failed to get laid yet!!
