Fight the guy off, no reason he should be talking to my girl.
Break up with her
Listen over to thier conversation
Walk in the room and introduce yourself
Roll your eyes and say, "Wow, I didn't realize you were into sophomoric humor."
Burst out laughing as if it is the funniest thing you've ever heard.
Giggle a little to be polite but then change the subject to something.
Movies and TV shows.
Start talking about basket-weaving in exquisite detail
Keep nodding, smiling and acting like you're interested
Ask a few more questions about said hobby, since it's clear this is something that's important to your date
Try to find a subject that you both know something about to assess whether you might share other interests with your date.
Flag a cab and head back home. Seriously, would it kill this person to make a little effort to woo you?
Smile and say "Sure, sounds good," but secretly feel uncomfortable all night and wish you could sneak home and change your outfit.
Agree to the plan but then coyly slip your bracelet/watch into your pocket for safekeeping, undo a button or two, and mess up your hair a little bit. You're sure you can fit in with your date's preferred crowd/locale if you try
Laugh and say, "Wow, I'm clearly overdressed for that, but if you'll excuse my formal attire, I'd like to beat you badly at a round of darts"
The guy should always pay
I think both should
Depends on the situation, don't mind either way
I'm a girl and I want to impress a guy by paying on dates
Yes, if I'm not connected physically/intellectually.
No, skinny or fat, I give everyone a chance.
No, it's important that I do have a physical attraction.
It depends on her/his attitude.
