When we have a free night, we go to the Metreon or catch a show at the Fillmore or browse the aisles at Amoeba. Some of our local pro athletes, on the other hand, spend their Friday evenings stuffing signing bonuses into G-strings. The Hustler Club, the Gold Club, Crazyhorse -- if you're an athlete, the velvet ropes dissolve in your path, and a dancer named Lexxi might whisper in your ear in a discreet room on the second floor. Watch the entrances to these places for a while, and you'll wind up with a good lineup card. Here, at least, the pros can almost score.
