every time.
no dog. no baby. exotic sports car. he was shot down in flames every time.
then he did the same while walking a nice dog. this time he got 4 phone numbers. he tried the same experiment again with a cute baby he was babysitting for a while and he had 100% success.
lastly, he did it again with an exotic sports car he rented and went back to zero success.
so the conclusion is that using a dog or a baby will increase the probability of a woman being attracted to you and giving you her number... which is obviously a very good start.
