A New Definition of "Small"

(Boring background information: Lyme disease is carried by the deer tick. It's really small.)

Evaluating the possibility of Lyme disease over the phone:

"How big was the tick that bit you?"

"Small."

"How small?"

"Really small."

"Smaller than the group number on an Aetna ID card?"

"About that size."

"Ah. Please come right in for a blood test."

Moral of the story: Could they possibly print the group numbers on an Aetna ID card *any* smaller!?!
