Kramer: (about Jerry) After he heckled Toby, she got so upset she ran out of the building. And a street sweeper ran over her foot, and severed her pinkie toe.
George: That's unbelievable!
Kramer: Yeah, then after the ambulance left I found the toe. So I put it in a Cracker Jack box filled it with ice, and took off for the hospital.
George: You ran?
Kramer: No, I jumped on the bus. I told the bus driver 'I've got a toe here buddy, step on it!'
