A Red Sox fan walks into a Boston pub

A Red Sox fan walks into a Boston pub and spots a guy wearing a New York Yankees cap. “Drinks for everyone here, bartender!” shouts the Red Sox fan. “Except for Mr. Yankees!”

The Yankees fan smiles and says, “Thank you!”

Infuriated, the Red Sox fan orders another round of drinks for everyone except Mr. Yankees, who, again, thanks the man. This goes on for a while, until Mr. Red Sox asks the bartender, “What’s the matter with that guy? I’ve ordered rounds of drinks for everyone but him, and all he does is thank me. Is he nuts?”

“No, he’s not nuts,” says the bartender. “He owns the place.”
