A Giants fan is in Baltimore for the weekend and decides to stop in at a bar. He pulls up to the bar and waits for the bartender. The bartender and the other patrons ignore the fan. Finally, he speaks up.
"Could I get a beer please?"

"We don't serve Giants fans. This is a Ravens bar."

"Look I just want one drink and then I'll leave."

The bartender pours him a drink and gives him the third degree.

"What are you doing in Baltimore?"

"I'm here for a taxidermist conference."

"What does a taxidermist do?" the bartender asked.

"Oh, I mount animals."

The bartender steps back, and then says, "Hey boys, don't worry about this one, he's one of us."
