Deep in The Heart of Texas

A Brazilian, attending a masquerade Halloween Ball, was dancing with a tourist girl who was wearing a map of Texas for a costume. Suddenly she slapped him hard and stalked off the dance floor.

"What the hell happened?" asked a friend who had witnessed the entire event.

"I'm not really sure." the man replied, rubbing his red cheek. "When she asked if I had ever been to Texas, I put my finger on Amarillo to show her, and she let me have it."
