Hello, I'm not a regular visitor on this forum but I thought I would share this with you guys. It's a funny "trick" I learned many years ago and just recently realized it might come in handy as a funny, short routine.

Guessing her shoe size
The size of your feet are the same length as the distance between the bend of your arm and your wrist. You need to know this in order to understand the routine. If you don't believe me, check it out for yourself (place your foot against your lower arm). You also need to know your own shoe size so if you don't, you need to find that out. In my case, my shoe size is 40 which is a good, even number.

"Hey, you know what? I can tell what shoe size you have without even looking at your feet. Don't believe me? Here, give me your arm. (hold her hand with your left hand and slide a finger with your other hand slowly from the bend of her arm towards her wrist). Your shoe size is.. XX. Is that correct?" (you should be close enough. You can proceed to explain the trick or just go on with another routine)

The trick is that when she is holding out her arm to you and you place the finger of your right hand against the bend of her arm you secretely measure her lower arm length with your own. This way you should be able to guess her shoe size. For example, if her lower arm is a few centimetres shorter than mine I would gess her shoe size is around 37-38.

It might take some practice to get it right but it's an easy trick. Be glad to take your input.

Cheers
