There are three cops that go to the same bar after work every night. Two of the cops are veterans and one is a rookie.

One night the rookie and one of the veterans are sitting around and the third one comes into the bar with the biggest grin on his face.

The other two cops ask him, "Why are you so happy?"
He tells them, "Well last night I had the best sex in my life with my wife. I had my pistol cocked and loaded under the pillow. When I was about to come, I fired a shot into the air. Her beardedclam got really tight and we both came at the same time."

The next night, the other veteran comes into the bar with a grin on his face and tells the other veteran, "Thanks for the advice. Last night I had the most incredible sex with my wife. I was doing her doggy style and when I was about to come, I fired my pistol. We both had a spontaneous orgasim. It was great."

The next night, the two veterans see the rookie come into the bar, pissed as hell, kicking chairs as he makes his way over to them.

The rookie says, "Well I took your advice! My wife and I were doing sixty-nine and I fired my gun! The femaledog almost bit off my d!ck and she sh!t in my face!"
