Clever way to get her phone number
Say you are going to perform a magic trick to victim.
Ask said person to write down their phone number on a piece of paper, but say you don't need the paper.
Ask them to add up all the digits of their phone number **excluding** the middle two.
Say something about how phone numbers are not entirely random, and that the middle two digits mostly **(say this exactly "in 99.9999% of cases this works")** formed from the addition of all the other digits divided by two + a special number that only you know, ask them for the addition number, then guess a random number. When it turns out to be wrong, ask for the sheet to check they did the maths right. Then turn to them and say, **"huh, I guess you are just a one in a million kinda guy/girl"**
