These are some the best;
Heres 10p to ring your mum to tell her your not coming home tonight darling. (This was b4 mobile phones)
Grab your coat, your pulled!
Ask her how she likes her egss in the monrning… wait for response, then u say fertlisesed!
ask her… did it hurt? she will say did what hurt? u reply when you fell from heaven.
ask her… Are you tired? coss you have been running through my mind all night. lol
ask her… is your dad a theif? she will say pardon or f**k off then you say, your dad stole the stars and put them in your eyes.
Theose are mega cheesy!
When i was traveling around aus and asia (many moons ago) me and my mates would play loads of games… here are some of them.. i still think they are timeless treasures
Go upto a girl, we like would do you know about laying floor tiles? Its just so random, and stupid… you then start doing your work. Or what do you know about changing alternators? allways a good ice breaker
Also a supid pick game is when out with mates (of course).. your not allowed to speak to a girl with out saying a stupid commment… some of the favorites would be..
Cor Blimey Girl, ive had some ugly birds but u take the biscuit. with this you would think its very rude… but when you do it to the most stunnning girl in the pub, its pretty funny (in our eyes anyway 
We also played a game which lasted 2 weeks lol, when talking to any female, at the end of every sentace you had to say Ding or Ding Dong. So the way u decide if it was Ding or ding dong, would be if you root her or not lol i.e. hiya darling, hows it going ding dong? u just keep slipping it in. Or you go into a shop to buy smokes, errrmmm i would like 20 B&H please ding
lmao they were good and funny times
