Inflation
 

A stagecoach bounced down a rutted road, heading for Dallas. In the coach were a Texan, a very busty lady, and a greenhorn from the East.
The greenhorn kept eyeing the lady. Finally he leaned forward and said, "Lady, I'll give you ten dollars for a blowjob."
The Texan was appalled. He pulled out his pistol, shot the greenhorn right between the eyes, and shoved his body out the door.
The lady gasped and said, "Thank you, sir, for defending my honor!"
The Texan holstered his gun and said, "Your honor, hell! Just trying to keep down inflation. Around here, a blowjob goes for two dollars."
