This morning I was in luck and was able to buy two cartons of  

Victoria Bitter beer cheap at the local supermarket.

I placed the boxes on the front seat and headed back home.  I stopped

at a service station for fuel where a drop-dead gorgeous blonde in a

short skirt was filling up her car at the next pump.

She glanced at the two boxes of beer, bent over and leaned in my

passenger window, and 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?"
