I've seen that lady before. She's always funny to watch.
I've got a "Hide the Salami" trick, but I'll need a female volunteer. What? Oh, seen that one before have you?
That lady was awesome, and double cudos to the audience for having a sense of humour.
For those who really don't know how the trick was done: she had a skin-colored cap on her right thumb where she could fit the scarf in. That's why her hands keep coming together when she walks away
