Budweiser method

Three men are walking down the street. One is from California, one is from New York, and the last is from St. Louis. A good looking woman walks by ... the man from California states "She’s about an 8." The man from New York states "No, no ... she’s a 6." The man from St. Louis says "Hell no, she’s a 1." The two men look at the guy from St. Louis and turn to each other and say, "Well, she was not that good looking." All three continue walking down the strip. As chance happens another woman walks by. She is more beautiful than the first. The man from California exclaims "9" The man from New York cries "8.5" The man from St. Louis says "2" The man from California and New York State, "I guess it takes all types." Finally an extremely beautiful woman crosses their line of sight. The man from California and New York simultaneously state "10" The man from St. Louis states loudly, "3.5" The man from New York asks the man from St. Louis, "What the hell is wrong with you?" "Are you gay?" "She was beautiful!" The man from St. Louis turns to him and says, "I’m using the Budweiser method." The man from California asks "What is that?" The man from St. Louis responds "The Budweiser method is to see how many Clydesdales it would take to pull her off my face."
