I've been thinking this one over for a while, and "hopping mad" is a gag I throw out when one-legged people come to mind.
After a year in the hospice, columnist Art Buchwald died and his spirit went to Heaven.However, when he arrived, he still only had one leg.
"Where is my other leg?" asked Art.
"We're not sure," said Saint Peter. "We've checked the warehouses, but there's a huge backlog in inventory. Plus, there's a problem with routing issues these days."
After a brief discussion, they gave Art a set of canes and told him to come back in six months.
Sure, Art had a set of wings like everyone else, but landings can be a real bitch with just one leg.
