Poker

The poker game had dwindled to four players, including Rock, a sports information director Rock had known for nearly thirty years, and some youngster whose juvenile behavior had everyone on edge.
The four agreed to play one more hand. Rock dealt each player five cards and was pleased to see he held two aces. That should be good enough, he thought.
But the young, cocky player had two threes and a joker. "Joker's wild, so that's three threes," he said.
"Bullshit," Rock said. "No one declared jokers were wild."
"I thought that was assumed," the kid said.
