Phil was at the bar one night, and complained about having a headache.

"I've got a beaut cure for a headache," said his mate Trev. "Whenever I 
have a headache I head home and I get my wife to give me a long, slow, wet 
blowjob. Never fails."

A week went by and they were in the bar again, talking. "Did you try my 
headache cure," asked Trev. "Yeah said Phil, worked great! Your house is 
nice, too!"
