Sally: I'm pregnant with your baby
John: Bitch, no your not
Sally: Your the only one I have has sex with
John: We didn't have sex, we didn't have sex because I got mines within two pumps
John: Yeah bitch, "The Two Pump Rule", now get the fuck out my house cause I'm not the father.
Jack: Did you fuck my Wife!!!!!!
Matt: (thinking to himself)- I did not fuck her because I jacked off in the bathroom until I was almost about to cum and then went onto the bed and put it in her and ejaculated on the second pump...therefore I did not fuck her....thanks to The Two Pump Rule
