We got on a train, after a transatlantic flight, in Italy with our then-18 month old, who was tired and fussy, and a college-aged woman came up and offered to bounce him for a few minutes. When we looked around, he was making the rounds of the entire train car, sitting on a lap here, getting bounced there, basically getting passed from hand to hand.
Italy: land of "we love children, but don't have many ourselves." Loved it!
