Saw the line yesterday "nice legs, what time do they open?". Tut tut. Where's all the romance gone? ;)
Best chat up thing I've had in a while was when I was complaining to a friend that I was getting attacked by mosquitoes. I said "I think I must be really tasty" whereupon the guy sitting on the other side of me (who I didn't even know was listening) leaned over and bit me on the shoulder. It was daft enough that it worked.
