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 veteran comes into the bar with the biggest shit-eating 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 hid my pistol cocked and loaded under the pillow. When I was about to come, I fired a shot into the air. Her pussy got really tight and we both came at the same time."

The next night, the other veteran comes into the bar with a shit-eating 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 orgasm. 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 bitch almost bit off my dick and she shit in my face!"
