A man rushed into a bar and breathlessly asked the bartender to pour him three straight scotches. The bartender complied, and watched as he downed them one after another. "Why three scotches?" the bartender asked as he paused for breath. "Well, to be honest, I'm celebrating my first blow-job." "Hell, congratulations, the next one's on me." "No, thanks," the young man replied, "if the first three didn't get the taste out of my mouth, I don't think another one will."
