This is a visual joke, so it won't work too well...Why are Jewish businessmen bald, with big ears and long bushy beards?
'How much?' (cupping your ears with your hands) 'My life!' (dragging your hands across the top of your head)
'I'll have to think about that!' (twirling beard with your hands)
You can always tell when you're in a Jewish neighbourhood - padlocks on the dustbins, and toilet paper hung out to dry...
