Leaving for Las Vegas

A man comes home from work to find his wife in the bedroom, packing her suitcase. 

"What the hell are you doing?" he asks. 

"I'm leavin' you for a better life," she replies. 

"Where do you think you're going?" he asks. 

"I'm going to Las Vegas," she answers. "I hear they pay £400 for a blowjob there." 

The man thinks for a minute, then gets his suitcase out, and starts packing his clothes. 

"What the hell are you doing?" his wife asks. 

"I'm going to Las Vegas, too," he answers. "I want to see how you live on £800 a year!"
