Begin by showing a mouse, while you explain that it is the first pet you used in your magic shows. The mouse works as "Judy the Mouse", by using your thumb inside it and wiggling it, pretending it is alive. After a few gags and stunts, put the mouse visibly into your back trousers pocket. Ask for a ring. Make a magic gesture and vanish the ring. Show your back trousers pocket, exposing the mouse and its tail, by rotating your body. Take out the mouse showing that the ring is hanging on in its tail now!!! Easy to perform, no reset needed, smooth working, perfect for table hopping.
