Yesterday morning I bought two cases of beer on sale at the Beer Store.
I placed them on the front seat and headed back home.

I stopped at a service station where a drop-dead gorgeous blonde was 
filling up her car at the next pump.

Although it was very cold she was wearing a very short skirt and a light 
jacket which was wide open.
She glanced at the beer, bent over and knocked on my passenger window.

With her bra-less breasts almost falling out her skimpy top she said, in 
a sexy voice:

"I'm a big believer in barter, old fella; Would you be interested in 
trading sex for beer?"

I thought for a few seconds and asked, "What kind of beer ya got?"
