Bartender

A brunette walks into a bar and says, ”Gimme an M L.” The bartender says, ” What’s an M L?” She says, ” A Miller Light.” Another Brunette walks in and says, “Gimme a B L.” The bartender says, ”What’s a B L?” She says, ”Bud Light.” A dumb blonde walks in and says, ”Gimme a 15.” The bar tender says,” What’s a fifteen?” She says,” 7&7, duh!”
