Blow Job Celebration

A man walks into a bar and orders 6 shots of tequila. The bartender asks, "Why so many buddy?" The man replies, "I'm celebrating my first blow job". The bartender says, "Well hell, congratulations, I will give you one on the house for free." The man says, "No thank you, if the first 6 shots don't get the taste out of my mouth one more won't make a difference."
