( For the benefit of non-Americans -Budweiser is a top selling beer in America. It has a familiar commercial showing huge Clydesdale draft horses drawing an old fashioned beer delivery wagon)

Three guys at loose ends in a bar are sitting at a table and rating women as they walk in. The guys, of course, are using the familiar "1-10" system.

A cute brunette walks in. The guys agree that she rates a 7. The bartender happens to be wiping up at a nearby table (it's a small bar) and hears them. He glances over and says: " Nah, she'a 3 on the Budweiser system".

The guys are amazed and tell him she's a really attractive girl. The bartender shrugs and says:" That's how I see it'.

Next, a really interesting redhead walks in. The guys are unanimous that she rates a 9. Again, the bartender is nearby and hears them. He looks over and says:" I see her as a 5 on the Budweiser system".

The guys are astonished. "How can you say that? She's knock down, drag out gorgeous!" The bartender shrugs:" That's the way I see her under the Budweiser system".

Finally, a 5'11" blonde strolls in. The guys are unanimous that she is a 10. Again, the bartender looks over and pronounces: " I see her as a 6 under the Budweiser system".

The guys have had it. One guy says to the bartender: " What the hell is this Budweiser system?"

The bartender says: " The number of Clydesdales needed to pull me off her".
