Feet

Vascular surgeons have a special obsession with feet. Whether they're getting their noses in close to slimy toes to inspect ulcers or wrapping their bare hands around a stranger's foot to feel for pulses, they rarely let a patient into the ward without first thoroughly inspecting their feet.

One ward round we happened upon an elderly man who'd been admitted overnight and the surgeon asked, "do you mind if I look at your feet?"

 "Yeah, sure" he replied, "suit yourself. I've only got two"

After a few minutes of prodding and poking the man mused, "If you keep looking long enough, you'll find somebody that's got three feet"

Wouldn't that be the vascular dream?
