Piggy Wings

Smith smiled and put his research paper on the pile.
“So, you grew a flying pig,” said Zambosio. “Good work, Smith.”
Smith opened the paper and pointed to a chart. “Actually, it’s just growing wings on pigs.”
“So they can’t fly?” asked Zambosio.
“No,” said Smith.
“Still,” said Zambosio, “growing a pair of wings on a pig still takes a lot of effort.”
“Actually, it’s just one wing per pig,” said Smith.
Zambosio took off his glasses. “What good is just one wing on a pig?”
“They’re quite delicious,” said Smith.
“At least pigs are tamer than buffalo,” said Zambosio.
